4 Welcome 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 96

TR-08 has three operational modes (ICX-250 supports mode I):

Although commonly referred to as the TR-08 standard, the R T 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 v oice channels as signed to this port are identifi ed
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 re lation between a channel number
and corresponding slot number for TR-08 is shown in the following table.

TM

digital loop carrier system.

• 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 channe ls to t ime s lo ts i s made pos sible by the
exchange of messages between the Local Digital Switch (LDS) and remote terminal (RT).

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 d B b y m oving the related switch position to “Off.” See the cha rt on page 27 for more de tail
on the switch settings.

Transmit / Receive path will be attenuated by 3 dB (+/– 0.5).

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 circu it bre aker, make sure tha t the cor rect ra ting of wir e is used .
It is recommended you use 20 to 18 gauge wire.

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.

Alarm Closure Plug (supplied)

Wire

(not supplied)

wire tightening screws

(located under adapter)

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 le ad must be conn ected to the ch assis using a N o. 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.
