Product Overview
TR-08
The TR-TSY-000008 BellcoreTM standard (commonly referred to as TR-08) describes the generic
requirements for interfacing between local digital switches and remote digital terminals via the
SLC 96TM 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
the T1 time slot number. The ICX-250 supports only Group A. The relation between a channel number
and corresponding slot number for TR-08 is shown in the following table.

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.

!!ATTENTION!! Changing the Supervision type
switches will result in all FXS calls on the affected 12
FXS line group to be reset to the idle state each time a
DIP switch setting is changed. This means any active
calls in that FXS line group will be dropped.

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.

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 ICX250 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.
