About the GE MDS Intrepid-HC HP OCBs
GE MDS Intrepid-HC HP RFUs and OCBs (Outdoor Circulator Blocks) can be chained in different ways for
different configurations.
Two types of OCBs can be used:
Type1 OCB
Type2 OCB
The main difference between the two types are the circulator directions. Depending on the configuration, OCB Type
1 or Type 2 are used together with waveguide shorts, waveguide loads, U Bends, C Bends, or couplers.
Each OCB has four waveguide access points: two in the front, and two at the rear. The diversity access point is
optional.
If the system is not configured for diversity, all the relevant access points on the OCB must be terminated using
waveguide shorts.
Type 1 OCB
Type 2 OCB

Chapter 2: Initial System Setup
General
After the system is installed and tested, and antenna alignment is performed, the next step is initial IDU setup and
configuration.
Initial setup procedures are performed on a craft terminal via a serial port connection.
Note:
Configuration procedures are generally performed using the NMS software supplied with MDS Intrepid-HC HP.
A description of the NMS and how to use it is provided in the NMS User Guide.
The craft terminal should be used only to perform the initial setup procedures described in this chapter. Once the
system is up and running, use NMS to maintain and operate the system on a regular basis.
Initial Setup Steps
The initial MDS Intrepid-HC HP setup procedure includes the following steps:
Procedures Performed using a Craft Terminal:
- Connecting to the IDU via the terminal port
- Defining IP addresses
- Setup Options
Procedures Performed using the NMS:
- Connecting to the Ethernet port
- Installing the software
- Setting the local TX frequency channel
- Specifying system information
- Configuring the local/remote transport
- Configuring trap forwarding

Defining IP Addresses
Before you can configure the MDS Intrepid-HC HP system, you need to define IP addresses using the craft
terminal.
The MDS Intrepid-HC HP includes two IP interfaces: an Ethernet interface, and a serial interface. Each interface
has its own IP address and IP mask.
The IP address is a four digit number separated by decimal points. Each IP address is a pair netid,hostid, where
netid identifies a network, and hostid identifies a host on the network. The IP mask separates between the netid and
hostid.
For example, if the IP address is 192.114.35.12 (11000000 01110010 00100011 00001100), and the IP mask is
255.255.255.0 (11111111 11111111 11111111 00000000), the netid is 192.114.35, and the hostid is 12.
An IP interface can only communicate with hosts that are on the same net (have the same netid). In the example
above, the interface can communicate only with hosts that have netid 192.114.35 (for 1 to 255).
If The transceiver has a frame to send to a host that is not on the Ethernet IP netid or the serial IP netid, the frame
should be sent to an intelligent device (usually a gateway) on the network. Such a device, known as a "default
router", will know how to send the frame over the internet. The default gateway should be a host on one of the
Transceiver interface netids.
The following figure shows how the transceiver is integrated in the local network.

To define IP Addresses:
1. In the main terminal program menu, select Configuration.
2. Select IDC.
3. Select Basic.
4. Select IP and define the addresses as described above.
Important After you set up IP addresses, restart the IDU to activate them.
Setup Options in the Terminal Program
The main menu in the terminal setup program includes the following options:
Configuration (1) - the main setup section in which you can configure the IDC, the right and left drawers,
protection, SNMP management, in-band routing, and other such parameters.
System Status (2) - used to obtain information about the different software versions currently used in the system.
Maintenance (3) - used to perform software upload, download, and reset.
Diagnostics (4) - used to perform loopbacks and obtain system information.
Logs (5) - used to view alarm and configuration log reports.

Additional Setup Using the NMS
Some of the initial setup procedures require the use of The NMS.
Once initial setup is complete, use The NMS to run the system on a daily basis.
Connecting to the Ethernet Port
1. Connect a crossed Ethernet cable from your PC to the Ethernet Port. If the connection is to a LAN (wall
connection) use the standard Ethernet cable.
2. Make sure the IP address on your PC is on the same sub-net as you defined in the MDS Intrepid-HC HP indoor
unit (in most cases, the first three numbers of the IP address must be identical, depending on the sub-net mask).

If the TX frequency was previously defined using the HyperTerminal, use this screen only to verify that the correct
frequency was set.
1. Select Configuration, RFU Left/Right, RFU Configuration, or click the RFU icon in the tool bar.
At the top of the window, the system displays TX/Rx ranges, the gap between them, and the channel
bandwidth.
RFU Configuration Window
Note: In the window shown above, the RFU illustration shows two antennas. Only one antenna appears in the
illustration if the IFC (IF Combiner) is not supported.
2. The RFU Parameters area is read-only. The Duplex Frequency value changes in accordance with the TX/RX
frequency values.
3. You can change the TX and RX frequencies of the ODU in one of the following ways:
Manually enter the TX frequency and/or RX frequency (6, 7, 8, 10, 11 GHz only) in the respective fields.
GE MDS Intrepid-HC HP Installation Guide
2-7

Or click the up/down arrows in the TX Channel field to select the channel (the frequency will be updated
accordingly).
For the Frequency Control area, note the following:
Only one standard is generally shown, predetermined by the ODU parameters. When the standard is unknown,
the TX Channel field will be disabled.
TX Channel selection is possible only when a predefined standard file was installed. In some cases, you may
be able to select more than one standard.
The Rx Frequency field is read-only for systems other than 6, 7, 8, 10, and 11 GHz.
The arrow on the right side in the Frequency Control area is green when communication exists between the
local and remote units. If there is no communication between the units, the arrow is red.
4. Select the XPIC Enabled option if you want to activate the XPIC mechanism.
With The transceiver operating in co-channel dual polarization (CCDP) mode, using the cross polarization
interference canceller (XPIC) algorithm, two STM-1 signals can be transmitted over a single 28 MHz channel,
using vertical and horizontal polarization. This enables double capacity in the same spectrum bandwidth.
Note: Setting XPIC for the right drawer will effect the left drawer as well, and vice versa.
5. Select Local Only if you want to frequency changes to affect only the local unit. Select Local + Remote if you
want frequency changes to affect the remote unit as well.
Note: If there is a communication failure between the local and remote units, the Local + Remote option will be
disabled.
6. In the Transmitter Configuration area, select TX Mute to block transmission to the remote unit. By default,
this option is not selected.
Select ATPC to activate the Automatic Transmit Power Control feature.
For Set TX Level, enter or select the designated signal level. Possible range is -10 to max power level. By
default, the transmit signal level is set to the maximum power level.
The Monitored TX Level field (read-only) displays the system's transmitted power level.
7. In the Receiver Configuration area, the Set Reference Rx Level field should be set to the Rx level to which
the actual level will be compared. This field is active only if ATPC is enabled.
Receiver Mode is the Rx path, which can be set to Main, Diversity, or Combined. This field appears only if
IFC (IF Combiner) is supported.
RSL Connector Source can be Diversity or Main. This field appears only if XPIC is not supported and IFC is
supported.
The Monitored Rx Level (Main) field is read-only and displays the received power level.
Monitored Rx Level (Diversity) is a read-only field that displays the received power level of the Diversity
channel.
8. Click Apply to save the settings.
9. Click Close.

Initial Setup for Intrepid-HC HP/T IDU
Initial Setup Steps for up to 9+1 Configuration
Cascading two Intrepid-HC HP/T IDUs at each site enables a configuration of up to 9+1 (10 carriers), or XPIC 7+1
with two additional carriers.
The setup steps for a configuration of up to 9+1, are identical to those of the configuration of up to 4+1 (see above)
except for the following differences:
You must configure all six IDCs using the HyperTerminal.
You must specify if you are using cascading mode, using the HyperTerminal
You must specify in which IDU the protected link will be defined.
To set the cascading mode:
1. In the main terminal program menu, select Configuration.
2. Select System configuration.
3. Select Cluster configuration.
Specify the number of sub-racks in the system. 1 for stand alone, or 2 for cascading mode.
Specify either 1 or 2 for the sub-rack number. The protected carrier will be in sub-rack 1.

Defining IP Addresses
Before you can configure the Intrepid-HC HP/T system, you need to define four IP addresses using the craft
terminal.
The Intrepid-HC HP/T includes three levels of two IP interfaces: an Ethernet interface, and a serial interface. Each
interface has its own IP address and IP mask.
You must configure an IP address for each of the three IDCs - a unique shelf number for each shelf in the cluster.
In addition, you must define same base IP address for every Intrepid-HC HP/T IDC. The address is a four digit
number separated by decimal points. Each IP address is a pair netid-hostid, where netid identifies a network, and
hostid identifies a host on the network. The IP mask separates between the netid and hostid.
For example, if the IP address is 192.114.35.12 (11000000 01110010 00100011 00001100), and the IP mask is
255.255.255.0 (11111111 11111111 11111111 00000000), the netid is 192.114.35, and the hostid is 12.
An IP interface can only communicate with hosts that are on the same net (have the same netid). In the example
above, the interface can communicate only with hosts that have netid 192.114.35 (for 1 to 255).
If Intrepid-HC HP/T has a frame to send to a host that is not on the Ethernet IP netid or the serial IP netid, the frame
should be sent to an intelligent device (usually a gateway) on the network. Such a device, known as a "default
router", will know how to send the frame over the internet. The default gateway should be a host on one of the
Intrepid-HC HP/T interface netids.
The Intrepid-HC HP/T cluster is managed as a single Network Element (NE) by the EMS.

The following figure illustrates an Intrepid-HC HP/T management model from an EMS/NMS point of view.
Each IDC calculates its own IP address, considering cascade shelf# and floor#: IP = IPbase + 3*shelf #+ floor#
where:
IPbase is dividable by 8 (i.e. = IPbase & 0xfffffff8),
shelf# = 0, which is the cascade master (the one with the protected carrier), or 1 for cascade slave,
floor# = 1, 2, or 3 (the number of the floor within the Intrepid-HC HP/T shelf).
In-band Management
In-band management of the Intrepid-HC HP/T link chain must be configured carefully due to a large number of
public IP address allocations. In addition, it should be noted that in-band management becomes a limiting factor for
chain length when only the Class C DCN is used.
The figure below illustrates the largest Class C in-band subnet (with CIDR = 26 bits, i.e. subnet mask
255.255.255.192).
The DCN shown in the figure makes use of the 192.168.1.64 in-band subnet. This subnet allows 62 nodes
192.168.1.65 - 192.168.1.126, and has a broadcast address of 192.168.1.127.
It is assumed that the Intrepid-HC HP/T at site A has a single GNE 1 assigned to one of the IDCs.
All three IDCs at site A have direct out-of-band IP connectivity with remote management applications (NMS,
SNMP Agent, Telnet). The remaining Intrepid-HC HP/T chain IP addresses are accessed via the GNE IDC.
2-16
MDS Intrepid-HC HP Installation and Operation
Download from Www.Somanuals.com. All Manuals Search And Download.
Note that the Inband bytes run through the upper level of the cluster.
The Ethernet interface of every Network Element (NE) is assigned the CIDR=/29 subnet, i.e. subnet mask
255.255.255.248. This allows 6 elements to be communicated over the interface. These addresses can be fully
utilized when two Intrepid-HC HP/T shelves are cascaded for 7+1 group protection.
The figure above shows “back-to-back” connected Intrepid-HC HP/T shelves at the same sites: B, C, and D, for
East/West chaining. Two NE IDCs (NE 2 and NE 3), at the same site, are connected over a PPPoE link.
This scheme allows four links of up to 7+1 (eight Intrepid-HC HP/T shelves, as shown, or sixteen shelves cascaded
in pairs) chained through the same NMS/SNMP Agent management, when IP addresses are allocated as described
above.
Notes:
1. The CIDR=/29 subnet allows external element communication (such as a laptop connected to the site B LAN)
only if there are less than six IDCs operating on two cascaded Intrepid-HC HP/T shelves. The subnet is not
sufficient for three Intrepid-HC HP/T cascading shelves. Three cascaded shelves require CIDR=/28 nodes
(subnet mask 255.255.255.240). This reduces the available number of chained links to 50%.

2. High protocol timing constraints (SNMP/TFTP) are expected in Intrepid-HC HP/T link chains due to the large
number of hops (each East/West site adds two in-band routing hops), and a large number of managed IDC
nodes.
The following slight optimization may be useful for a chain topology (but not for a ring):
One of the in-band NE management channels is configured as a Default GNE Direction, assuming the channel
leads to the nearest GNE under normal conditions. Then, in-band routing chooses this channel as a first priority
for every “in-band packet” generated internally, or received from the Ethernet interface.
To define IP Addresses:
1. In the main terminal program menu, select Configuration.
2. Select System configuration.
3. Select IDC configuration.
4. Select IDC Basic configuration.
5. Select IP.
6. Define the addresses as described above: element IP and basic IP of the units.

6. For Revertive Link, select the carrier that will be connected to the +1 modem. Your selection will be used in
cases where a switch occurs and then the system returns to normal operation.
Examples
Revertive = Extra Traffic
If a major alarm occurs at site A, a request is sent to site B to transmit through the Extra Traffic channel. The
switch that is performed is Hitless (up to 10 ms), and the Extra Traffic channel will no longer exist on both
sides by definition (generally, the system can protect up to two faults at different sides). The moment the alarm
is cleared, the +1 (Extra Traffic) modem will refer to the input from the +1 MUX.
Revertive = None
Each carrier MUX will receive two inputs: its own modem, and the +1 modem. The Extra Traffic channel will
not exist. Data to the MUX (for each of the defined carriers) will be received from its own modem until the
GE MDS Intrepid-HC HP Installation Guide

Download from Www.Somanuals.com. All Manuals Search And Download.
first hitless fault. When the fault is cleared, the MUX will receive data from two sources: the +1 modem, and
its own modem, meaning the next fault in this channel will be errorless (if other carriers will fail, the data will
be hitless).
Revertive = Carrier#X
MUX number X will always receive two sources: the +1, and its own, unless there is a fault in another carrier.
If MUX number X receives two sources, and a fault occurs, the switch is errorless. In all the other cases, the
switch is hitless.
7. For Revertive Switch Timeout, specify the period (in seconds) after which the revertive mode will be
activated.
8. For High Priority Threshold, click the drop-down list and select the criteria upon which the system will
perform a switch to the channel you chose as high priority.
The options include: Baseband Loss of Frame, Baseband Excessive BER, Baseband Signal Degrade, and Early
Warning
9. In the priority table, designate the high priority channel(s). A high priority channel will be switched first when
the criteria chosen for the threshold is met, even if a major fault occurs in a different channel.
The Priority Level options include:
Normal - regular operation according to the N+1 mechanism
High Priority
Not Protected – stand-alone channel without protection

Site Acceptance Checklist Notes
The following notes provide important additional information about the Site Acceptance Checklist.
1. Antenna Mounting
Mounting pole is of sufficient height to clear local obstructions, such as parapets, window cleaning
gantries, and lift housings.
Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety hazard. No
person should be able to walk in front of, or look directly into the path of the microwave radio beam.
Where possible, the pole should be away from the edge of the building.
Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause problems during
antenna alignment.
Mounting pole is grounded as per site specifications. All operators and site owners have specific
requirements regarding the grounding of installations. As a minimum, typical requirements are such that
any metal structure must be connected to the existing lightning protection ground of the building. Where
it extends beyond the 45-degree cone of protection of existing lightning conductors, additional lightning
protectors should be installed.
All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.

2. Antenna
Antenna is grounded as per site specifications. See the third point in the Antenna Mounting section above.
Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an antenna of 1.2
m or larger, an extra sway brace is fitted to the mounting frame of the antenna. This sway brace should
not be mounted to the same pole as the antenna, but should be installed directly back to the tower or an
alternative point.
Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas have moisture
drain plugs installed at various points around the antenna. The purpose of these plugs is to allow any
moisture that forms on the inside of the antenna or radome to drip out and prevent a pool within the
antenna. Only the plugs at the bottom of the antenna, after installation, should be removed. All other
plugs should be left in position.
3. RFU (RF Unit)
The RFU is grounded as per installation instructions. See the third point in the Antenna Mounting section
above.
The RFU Polarization is as per link requirements and matches the polarization of the antenna.
4. Indoor Unit
The main traffic connections are correctly terminated and crimped as per cable and connector
manufacturer instructions. All fiber optic patch leads should be routed carefully and efficiently, using
conduits to prevent damage to the cables.
All other user terminations are secure and correctly terminated.
All labeling is complete as per site requirements. Labeling is specific to each customer. At a site with
only one installation, labeling may be unnecessary. However, at sites with multiple installations, correct
and adequate labeling is essential for future maintenance operations.
Typical labeling requirements include:
Antenna labels - for link identity and bearing
RFU labels - for link identity, frequency, and polarization
Coax cable labels - for link identity, close to the RFU, IDU, and either end of any joint
IDU labels - for link identity

2+0 XPIC Commissioning Procedure
Scope
This section describes the recommended commissioning tests for a GE MDS Intrepid-HC HP radio link in a 2+0
XPIC Co-Channel-Dual-Polarization configuration.
The purpose of the commissioning tests is to verify correct and proper operation of the product.
Important! Since operation of the XPIC system depends on correct installation, make sure the guidelines for
XPIC system installation provided below are followed correctly.
XPIC Installation Guidelines
Antenna and RFU Installation
1. Install the dual polarization antenna and point it in the direction of the other site.
2. Install the two RFUs on a dual polarization antenna using the appropriate mounting kit, and mark the
RFUs with V and H respectively.
IDU-RFU Cable Installation
1. Install two cables between the RFUs and the drawers (IDMs). Note that cable length difference should not
exceed 10 meters.
2. Mark the cables with V and H respectively, and make sure V is connected to the right drawer and H is
connected to the left drawer.
3. Mark the drawers respectively.
Antenna Alignment
1. Power up drawer V on both ends of the link and configure it to the desired frequency channel and
maximum power.
2. Align the antennas, one at a time, until expected RSL is achieved. Make sure the achieved RSL is no more
than +/-4 dB from the expected level.
Polarization Alignment
Polarization alignment is required to verify that the antenna feeds are adjusted, to ensure that the antenna XPD
(Cross Polarization Discrimination) is achieved.
Polarization adjustment should be done on one antenna only.
3-12
MDS Intrepid-HC HP Installation and Operation
Download from Www.Somanuals.com. All Manuals Search And Download.
1. Power up drawer V on both ends of the link and record the RSL reading on one end.
2. Power off drawer V on that end and power on drawer H.
3. Check the RSL obtained on this RFU on H pol, and compare it to the RSL obtained by the RFU installed
on the V pol.
4. Verify that XPI (Cross Polarization Interference) is at least 25 dB
where:
XPI = RSLPOL ꢁ RSLXPOL
RSLPOL ꢀ Link RSL with the same polarization used at both sites.
RSLXPOL ꢀ Link RSL with orthogonal polarizations used at both sites.
5. If XPI is less than 25 dB, adjust the feed polarization by opening the polarization screw and gently rotating
the feed to minimize the RSLXPOL
.
Note that polarization alignment is not always possible since the RSLXPOL may fall below the sensitivity
threshold of the RFU.
It is also recommended to try to maximize the XPI as much as possible, by aligning the polarization.
XPIC Commissioning Tests
Individual Link Verification
Before operating in XPIC configuration, each of the links (V and H) should be commissioned individually in
order to verify its proper operation.
1

Power up only drawer V at both ends and verify its frequency channel and TX power configuration.
Verify that the RSL is no more than +/-4 dB from the expected level.
Run BER stability test on the link for at least 15 minutes to ensure error-free operation.
Power up only drawer H at both ends and verify its frequency channel and TX power configuration.
Verify that the RSL is no more than +/-4 dB from the expected level.
Run BER stability test on the link for at least 15 minutes to ensure error-free operation.
XPIC Configuration Verification
1
Using the XPIC cable, connect the two RFUs at each end to the TNC connectors. Make sure the
cable is no longer than 3 meters.

IN CASE OF DIFFICULTY...
GE MDS products are designed for long life and trouble-free operation. However, this equipment, as with

you in the event that servicing becomes necessary.

FACTORY SERVICE
Component level repair of this equipment is not recommended in the field. Many components are installed
using surface mount technology, which requires specialized training and equipment for proper servicing.
For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best
equipped to diagnose, repair and align your radio to its proper operating specifications.
If return of the equipment is necessary, you must obtain a Service Request Order (SRO) number. This
number helps expedite the repair so that the equipment can be repaired and returned to you as quickly as
possible. Please be sure to include the SRO number on the outside of the shipping box, and on any corre-
spondence relating to the repair. No equipment will be accepted for repair without an SRO number.
SRO numbers are issued online at www.GEmds.com/support/product/sro/. Your number will be issued
immediately after the required information is entered. Please be sure to have the model number(s), serial
number(s), detailed reason for return, "ship to" address, "bill to" address, and contact name, phone number,
and fax number available when requesting an SRO number. A purchase order number or pre-payment will
be required for any units that are out of warranty, or for product conversion.
If you prefer, you may contact our Product Services department to obtain an SRO number:
Phone Number: 585-241-5540
Fax Number: 585-242-8400
The radio must be properly packed for return to the factory. The original shipping container and packaging
materials should be used whenever possible. All factory returns should be addressed to:

Product Services Department
(SRO No. XXXX)
175 Science Parkway
Rochester, NY 14620 USA
When repairs have been completed, the equipment will be returned to you by the same shipping method
used to send it to the factory. Please specify if you wish to make different shipping arrangements. To inquire
about an in-process repair, you may contact our Product Services Group using the telephone, Fax, or E-mail
information given above.
