Outgoing call process
To place outgoing calls, users can either pick up the handset on the telephone or
press the line key. For a detailed description of the outgoing call process, refer to
the sample illustrations beginning on page 14.
Incoming call process
When someone places a call through the host PBX to a Meridian Digital
Telephone IP Adapter unit, the RLC connects to the remote unit. The host PBX
then completes the call normally. If the RLC cannot establish a connection, the
call rings until the host PBX forwards the call to voice mail. Refer to Chapter 6,
“Using the digital telephone”, for a more detailed description of the incoming
call process.
Host-controlled call mode
When you place a call to someone at the host site, or when someone from the
host site calls you, the call is in host-controlled call mode. Calls in host-
controlled mode are routed through the host PBX. Refer to the sample
illustrations beginning on page 14.

System security
There are two levels of security that you can set to control access from Meridian
Digital Telephone IP Adapter units to the RLC on the host PBX. This section
describes these security levels and how you can manage them using
Configuration Manager.
No security
When no security measures are used, the RLC accepts incoming calls from all
Meridian Digital Telephone IP Adapter units.
Use this level with caution as it exposes the RLC to unauthorized use. For
example, No security allows a user from an unauthorized remote site can
accidentally, or intentionally, connect to the RLC. With this connection made,
the unauthorized user can now place long distance phone calls through the RLC
and the host PBX.
Security identifier
When you choose the security identifier level of security, the Meridian Digital
Telephone IP Adapter automatically sends its configured security identifier
(password) for each connection request. The RLC compares the identifier
configured to the RLC port with the identifier assigned to the Meridian Digital
Telephone IP Adapter. If the identifiers match, then the RLC grants the
requested connection.
If the identifiers do not match, then the RLC records an event in the Meridian
Digital Telephone IP Adapter system log. You can view the system log in
Configuration Manager. The telephone displays HOSTLESS MODE, indicating that
communications with the host PBX are down.

Network considerations
Refer to the Remote Office Network Engineering Guidelines
(NTP 555-8421-103) for detailed information on planning and preparing your
network for the addition of IP Adapter units. The Meridian Digital Telephone IP
Adapter unit communicates with the host PBX using the IP network. To use the
Meridian Digital Telephone IP Adapter unit in these networks, you must
consider the issues described in this section.
IP addressing and routing
To place and receive calls over the IP network, you must:
!
!
physically connect the Meridian Digital Telephone IP Adapter unit to the IP
network
assign a unique IP address and a subnet mask to the Meridian Digital
Telephone IP Adapter unit, unless using Dynamic Host Configuration
Protocol (DHCP)
Note: Similarly, you must assign a subnet mask, gateway, and unique IP
address to the RLC on the host PBX.
!
have the ability to send and receive traffic to and from the RLC on the host
PBX
Determining DHCP Assigned IP Addresses
If you use DHCP at the remote location, determine the Remote Office Unit's IP
address by checking the Network statistics for the RLC through Configuration
Manager. Log onto Configuration Manager, choose the RLC as the Device Type,
and then access Alarms/Stats/Logs ➝ Network Statistics. Enter the Unit ID of
the Remote Office unit that you want to review the statistics for. The DHCP
assigned IP address displays at the top of the window.
Note: If you are using a Network Address Translation (NAT) router at the
remote location, the IP address provided is a NAT address. To access the Remote
Office unit using Telnet, ensure that the NAT router allows Telnet access to TCP
port 23, and for upgrades, TCP port 69.

Deployment
This section presents the Meridian Digital Telephone IP Adapter unit
deployment models (options) that are supported by Nortel Networks.
Transport media
You can only configure the Meridian Digital Telephone IP Adapter unit on the
RLC to use the IP network. For further details on this configuration, refer to
Priority under Remote Port Configuration in the Reach Line Card Installation
and Administration Guide (NTP 555-8421-210).
Network Address Translation
Some network routers run the Network Address Translation (NAT) protocol that
allows multiple devices in the IP network to share the same broadband IP
address. An alternative to running the NAT protocol is to have the network
administrator provide each device with its own broadband IP address.
Meridian Digital Telephone IP Adapter units support NAT functionality, if this
functionality is enabled on your network. You can only connect a single
Meridian Digital Telephone IP Adapter unit behind a NAT router. You can
connect multiple Meridian Digital Telephone IP Adapter units behind a PNAT
router. A PNAT router is a port number and network address translation router. If
you are not sure whether yours is a NAT router or a PNAT router, check with
your vendor.
You must configure your Meridian Digital Telephone IP Adapter unit for IP
permanent allocation if it is connected behind a NAT router. You can assign a
static IP address to your Meridian Digital Telephone IP Adapter unit, or you can
use DHCP to obtain its IP address.

Overriding an automatic offline event from the host PBX
If the host PBX attempts to process an offline event while you are on a host-
controlled call, you are alerted by both an audible alert and a display message
indicating that you are about to go offline in 30, 20, or 10 seconds. If you ignore
this warning, your call disconnects.
To prevent your call from being disconnected, enter the online SPRE code. You
can do this without putting your call on hold first. The online SPRE code cancels
the offline event, leaving your telephone online until the next offline event
occurs.
