DID Interface Board
The Direct Inward Dial Interface Board (DIDB) provides four (4) analog DID CO interface ports.
The DIDB can be optionally equipped with a DTMF Receiver Unit (DTRU) daughter board to
detect DTMF tones.
Installing the DTRU Module
1. Unpack the DTRU Module from its antistatic conductive bag.
2. Locate the CN1 and CN2 connectors on the DTRU module.
3. Locate the CN1 and CN2 connectors on the DIDB.
4. Position the DTRU module so that...

Digital CO/PBX Line Interface Boards
Digital CO/PBX line interface boards include the T1 interface board (T1IB), primary rate
interface board (PRIB), basic rate interface board (BRIB), and Voice over internet protocol
(VOIP) card.
T-1 Interface Board
The T-1 Interface Board (T1IB) provides the T-1 (1.544Mbps, 24-Voice Channel) digital
interface circuit, control circuitry, and synchronous clock control circuits....

Chapter 3 - System Installation
The T1IB contains 2 switches (SW1 and SW3) and 3 connectors (CN1, CN2 and CN3). The clock
selection switch is used for control synchronous clock. The Line Build-Out switch is controlled
by distance between theXTSSystems and a CSU and SW1 #4 is used for loopback control.
The clock control cable should be connected by a daisy-chain method when more than one
T1IB board is installed. When the clock control cable of the T1IB is connected by daisy-chain...

†This board supports standard D4 framing format with robbed bit signaling. Extended
Super Frame (ESF) format is also supported.
†The board requires an external CSU unit.
†The T1 board can accept two DTRU4 units in a daughter board type arrangement. Each
unit has 4 DTMF Receivers installed on it.
†The board has a 15-pin D Sub connector for connection to a CSU unit.
†The card ejector tabs are color coded white.

T-1 Ordering Information:When ordering a T-1 circuit from a carrier, request either D4
framing and Alternate Mark Inversion (AMI) Line coding using the superframe (SF) or the
Extended Superframe (ESF-B8ZS) format. The following are additional ordering information
specifications:

4. Position one of the DTRU4 modules so that the CN2 and CN1 connectors align with the
CN8 and CN9 connectors on the T1IB respectively.
5. Push the DTRU4 module onto these connectors to seat it securely.
6. Position the second DTRU4 module so that the CN2 and CN1 connectors align with the
CN4 and CN5 connectors on the T1IB respectively.
7. Push the DTRU4 module onto these connectors to seat it securely.

The PRIB accepts two DTRU4 boards.
Installation
1. Insert the PRIB card(s) into the desired card slot.
2. If installing a single PRIB, set SW2 to the ON position.
If multiple PRIBs are being installed, set SW2 to the ON position on the first card and SW2
on all other cards to the OFF position.

Basic Rate Interface Board
The Basic Rate Interface Board (BRIB) interface provides four Basic Rate Interface circuits. Each
circuit is comprised of two bearer (64Kbps each) and one data (16Kbps) channels (2B+D).
When a BRIB is programmed into theXTSsystem, the...

Installation
1. Insert the BRIB card(s) into the desired card slot. Up to seven BRIB cards can be installed in
anXTSCabinet, with a maximum of 18 per system.
†If installing a single BRIB, set switch 4 on SW2 to the ON position.
†If multiple BRIB cards are being installed, set switch 4 on SW2 to the ON position on
the first card and switch 4 on SW2 on all other cards to the OFF position. Switch 4 on
SW2 determines if the board is the Master Clock...
