Welcome  
Product Overview  
TR-08  
TM  
The TR-TSY-000008 Bellcore standard (commonly referred to as TR-08) describes the generic  
requirements for interfacing between local digital switches and remote digital terminals via the  
TM  
SLC 96 digital loop carrier system.  
TR-08 has three operational modes (ICX-250 supports mode I):  
• Modes I & III are non-concentrated and provide unique mapping between channel  
numbers and DS1 time slots.  
• Mode II is concentrated and there are no pre-determined relationships between the  
channels and timeslots. This allocation of channels to time slots is made possible by the  
exchange of messages between the Local Digital Switch (LDS) and remote terminal (RT).  
Although commonly referred to as the TR-08 standard, the RT channel numbering scheme supported  
by the ICX-250 unit is described in section 9.9 of the Bellcore publication TR-TSY-000057.  
The ICX-250 provides SLC-96 Frame Format and Data Link.  
When a T1 port is configured for TR-08 format, the voice channels assigned to this port are identified  
by “channel number” (according to the TR-TSY-000008 document), which may be different from  
theT1timeslotnumber. TheICX-250supportsonlyGroupA. Therelationbetweenachannelnumber  
and corresponding slot number for TR-08 is shown in the following table.

Installing the ICX-250  
Wall Mounting  
Prior to wall mounting check to see if the environment is stable and free  
from any extreme temperatures, humidity or vibrations of any sort. The  
unit should be mounted with the fan to the top with at least 2 inches of  
clear space on the sides, above, and below for adequate air flow. Allow at  
least 6 inches for cable clearance and access to switches.  
When attaching unit(s) to a wall make sure that appropriate fasteners such  
as masonry anchors, heavy duty wood screws or expansion bolts are used  
for heavy objects.  
!!ATTENTION!! Set all options prior to installing  
mounting brackets, top cover cannot be removed  
once brackets are in place.  
Note: Additional support hardware may be necessary  
(not included with unit) to secure the unit properly to  
the wall. If the surface is not solid enough to hold the  
unit and attached cabling, it is recommended that a  
small piece of 3/4” plywood be fastened to the wall before  
attaching the unit. This will help ensure a more stable environment  
.

Internal DIP Switches  
The ICX-250 comes equipped with either 12 FXS or 24 FXS analog voice  
ports depending on which model you purchase. For illustration purposes  
the 24 FXS port model is shown. There are a total of eight internal DIP  
switches (five on the main circuit board, and three on the auxiliary  
board).  
Note: The individual switches on each switch  
assembly operate independently of one another.  
DIP Switch Settings  
Locate the DIP switch internally that describes the function you wish to  
effect. The top cover of the unit displays the configurable options. Use the  
tip of a small object to change the switch settings. The switches will glide  
easily into place.  
CAUTION  
Access to the internal switches is accomplished by  
opening the case. Use care when opening the case to  
avoid damaging the internal components.  
TIP  
Switch setting  
changes will  
take effect  
immediately.

Description: These are eight position DIP switches used to set Transmit and Receive FXS  
attenuation (TLP Setting).  
Factory Setting: 3 dB (OFF) The DIP switch layout shown above is an example using 3 dB of  
attenuation on the Transmit side (positions 2,4,6,8 off) and 9 dB on the Receive side (positions  
1,3,5,7 on). If it is necessary to change the Transmit setting to attenuate the line by 9 dB, the related  
switch position(s) would be set to the “On” setting. Receive side settings would be changed from  
9 dB to 3 dB by moving the related switch position to “Off.” See the chart on page 27 for more detail  
on the switch settings. 3dB: Transmit / Receive path will be attenuated by 3 dB (+/– 0.5). 9dB:  
Transmit / Receive path will be attenuated by 9 dB (+/–0.5).  
!!ATTENTION!! The above FXS Port settings are  
repeated for each of the 12 or 24 lines.

OFF: FXS Ports 1-12 are mapped onto T1 time slots 1-12 and FXS Ports 13-24 are mapped onto  
T1 time slots 13-24.  
Swap (ON): FXS Ports 1-12 are mapped onto T1 time slots 13-24 and FXS Ports 13-24 are  
mapped onto T1 time slots 1-12. Swap is available only on switch 7 and is applicable only on the  
12 port model.  
Depending on the services provided by your carrier for voice and data, you may need to reassign  
the FXS timeslots of the 12 FXS port model. Timeslots 13 to 24 will be assigned in order to  
allocate data to the lower timeslots.  
The DIP switch setting shown in the illustration above is for Switch S7 ONLY.

External DIP Switches  
The ICX-250 is equipped with five external DIP switches (four - 12 dip  
switches, and one - 7 dip switch) located on the rear panel of the unit.  
These switches are used for Data Port and T1 Configuration. Each switch  
is set to a preconfigured factory setting when shipped. The illustration  
below outlines the location of these DIP switches.  
Note: The individual switches on each switch  
assembly operate independently of one another.

Power Requirements  
Electrical Installation  
47  
Power Requirements  
The installation site should have a 120VAC power receptacle readily  
available to power up the unit. The unit can also be powered by –48VDC  
or +/–24VDC.  
Power Installation  
A.C. Power Installation  
The ICX-250 unit is equipped with an AC receptacle located on the back  
of the unit.  
D.C. Power Installation  
When wiring to an external power source, such as a battery rack, fuse  
panel, or circuit breaker, make sure that the correct rating of wire is used.  
It is recommended you use 20 to 18 gauge wire.  
Note: The ICX-250 unit can have both an AC and DC  
power source connected to it at the same time. These  
two power inputs will share the power load. However,  
if one fails the other will carry the full load.

Power Requirements  
Alarm  
The ICX-250 unit is equipped with an external alarm connector (located  
on the rear panel of the unit) that will close in the event of an alarm  
condition such as: T1 failure, internal failure, or power failure. A Red  
alarm is detected by the T1 interface and responded to by issuing the  
yellow alarm signal on the T1. The figure below illustrates the alarm  
connector. It is recommended you use 26 to 24 gauge twisted-pair wire.

Grounding Requirements  
Due to the UL regulatory requirements, a mounting stud is required for  
connection of the AC input earth ground lead to the ICX-250 chassis.  
The ground lead must be connected to the chassis using a No. 6 nut and  
lock washer combination. The mounting location is labeled with the IEC  
417 No. 5019 symbol ( ) to identify this as the AC earth ground  
connection point. This mounting stud is located next to the IEC 320 AC  
input connector.  
The loop battery return and the FXS digital and analog circuitry must  
share a common ground. The access point on the back panel of the ICX-  
250 product allows connection to an external battery return lead which  
will be physically connected to the FXS circuit ground. This access point  
is provided as part of the DC power input connector.

Slide Switch Settings  
The ICX-250 is equipped with five external slide switches (four - 3  
position, one - 2 position) located on the front panel of the unit. They are  
used for T1 and Data Port test and Loopback Transmit / Receive paths.  
Each switch is factory set to the off position. The switches should be  
checked to be sure positioning hasn’t changed during shipment. The  
illustration below outlines the location of the slide switches.  
Locate the slide switch on the front panel that implements the function  
desired. Use the end of a small object or the tip of your finger to change  
the switch settings.

GENERAL  
INFORMATION  
WARRANTY/SOFTWARE  
The Product and Software warranty policy and warranty period for all  
Products of ADC Telecommunications, Inc. (hereinafter referred to as  
ADC) is published in ADC’s Warranty/Software Handbook. Contact the  
Business Broadband Group (BBG) Technical Assistance Center at 1-800-

(outside U.S.A. and Canada) for warranty or software information or for a  
copy of the Warranty/Software Handbook.  
REPAIR/ADVANCE REPLACEMENT POLICY  
All repairs of ADC Products must be done by ADC or an authorized  
representative. Any attempt to repair or modify ADC Products without  
prior written authorization from ADC shall void ADC’s warranty.  
If a malfunction cannot be resolved by the normal troubleshooting  
procedures, call the BBG Technical Assistance Center at 1-800-366-3891,  
extension 3223 (in U.S.A. or Canada) or 612-946-3223 (outside U.S.A.  
and Canada). A telephone consultation can sometimes resolve a problem  
without the need to repair or replace the ADC Product.  
If, during a telephone consultation, ADC determines the ADC Product  
requires repair, ADC will authorize the return of the affected Product by the  
issue of a Return Material Authorization number and complete return  
shipping instructions. If service is affected, ADC can arrange to ship a  
replacement Product when available from designated inventory. In all cases,  
the defective Product must be carefully packaged to eliminate damage, and  
returned to ADC in accordance with issued ADC instructions.  
REPAIR CHARGES  
If the defect and the necessary repairs are covered by warranty, Buyer’s  
only obligation is the payment of all transportation and associated costs in  
returning the defective Product to the location designated by ADC. ADC,  
at its option, will either repair or replace the Product at no charge and  
return the Product to Buyer with transportation costs paid by ADC, only

percent (20%) of Product list price charged for any returned Product  
found to be Out of Warranty, or one hundred percent (100%) credit for
