 DM/V1200BTEPEQ Media board 

(“board”) is a high-density, high-performance, 

network interface board with four T1/E1 digital 

network interfaces in a full-length PCI Express form 

factor. 
The DM/V1200BTEPEQ Media board includes the 

following components, shown in the Physical 

Layout illustration:
RJ-48C jacks: Four connectors to T1 or E1 trunks.
General Network Interface Alarm LED: 

Indicates when an alarm condition is present on 

one or more of the trunks.

Reset LED: Indicates when the board is in the 

reset state.

Power LED: Indicates when board power is good. 
SW1: Rotary switch used when setting board ID.
JP5: Boot-up Loopback Mode jumper. When 

unlinked, all trunks are in loopback mode from 

power-on until download completion. Factory 

default is loopback enabled (pins not linked, clip 

installed over one pin only).

Alarm/status LEDs: During power-up, the 16 

LEDs indicate Power-On Self Test (POST) status. 

After the board is started, each column of four 

LEDs indicate the status of one trunk. The green, 

yellow, and red LEDs indicate normal operation 

or Carrier Failure Alarms (CFAs) for each trunk as 

shown in the following table, and the Loopback 

LED indicates when the respective trunk is in 

loopback mode.

Power Budgeting Jumper P10: 3-pin jumper to 

set how the board responds to the system power 

budgeting function. 

■

P10 jumper in pins 2-3: Board adheres to 

power budgeting values set by system. 

■

P10 jumper in pins 1-2: Board ignores power 

budgeting values set by system.

Factory default is P10 jumper in pins 2-3. 

CT Bus Connector: H.100 telephony bus 

connector. 

P5: CT Bus termination jumper block. Only the 

boards in the end positions of a CT Bus cable 

should be terminated. Factory default is 

unterminated (clip installed over one pin only). 

PCI Express connector: Host bus connector. 

Compatible with x1 or larger PCI Express Link 

connectors.

Power-off Loopback Mode jumpers: Pairs of 

jumpers to set the power-off loopback mode for 

each trunk. Factory default is loopback enabled 

for all trunks (all pairs of pins linked).

■

JP3X11 & JP4X11: Trunk 1 loopback mode.

■

JP3X12 & JP4X12: Trunk 2 loopback mode.

■

JP3X13 & JP4X13: Trunk 3 loopback mode.

■

JP3X14 & JP4X14: Trunk 4 loopback mode.

Additional information about the DM/V1200BTEPEQ 

Media board is available from a number of sources, 

such as via its product data sheet, which is 

accessible at 

http://www.dialogic.com/products/list.asp. 

The product data sheet provides a functional 

description of the DM/V1200BTEPEQ Media board, 

as well as information about its applications, 

configurations, features, and technical 

specifications.
Refer to the Release Guide and the online Release 

Update for your Dialogic

®

 System Software release 

to verify that the DM/V1200BTEPEQ Media board is 

supported in the release, and for information on 

any new features or issues that may relate to it.
The Regulatory Notices document that is packed 

with each DM/V1200BTEPEQ Media board contains 

safety warnings and national requirements for 

proper operation of telecommunications 

equipment.

CAUTION: All computer boards are sensitive to 

electrostatic discharge (“ESD”). Handle all static-

sensitive boards and components at a static-safe 

work area, and observe anti-static precautions at 

all times.

If you are not familiar with ESD safety precautions, 

visit 

http://dialogic.com/support/hwinstall

 to learn 

more.

Unpack the board according to the following steps:
1. Prepare a static-safeguarded work area. 
2. Carefully remove the board from the shipping 

carton and anti-static packaging. Handle the 

board by the edges and avoid touching the 

board's components.

3. Lay the board on the static-dissipative work 

surface.

Note: Place boards in static-shielding bags when 

carrying boards from station to station.

CAUTION: Do not remove the board from the 

anti-static packaging until you are ready to install 

it. Observe proper anti-static precautions at all 

times.

The DM/V1200BTEPEQ Media board uses Plug and 

Play technology to simplify installation. No user 

configuration is required for IRQ or memory 

address.
The DM/V1200BTEPEQ Media board has the 

following manually configurable options:

■

Board ID 

■

CT Bus termination

■

Power-off loopback mode

■

Boot-up loopback mode

■

Power budgeting (see Choosing a Slot section 

below)

When the system is started, each Dialogic

®

 

telecom board is assigned a board instance ID 

number that programs can use to identify 

individual boards in a multi-board system. The 

setting of SW1 controls the generation of the 

instance numbers.
Windows Systems: In a Windows system, leave 

SW1 set to the 0 position (the factory default 

setting) on all Dialogic

® 

telecom boards. This 

setting causes the system software to assign 

instance numbers geographically, based on the 

bus and slot numbers. Note that there is no way 

to know what the instance numbers will be until 

the system is started and configured, and the 

instance number for any given board is likely to 

change when there is any change in the number 

or arrangement of boards in the system.
You can read the ID numbers assigned to the 

boards in the Dialogic

®

 Configuration Manager 

(DCM) tool after you start the system.

Linux Systems: In a Linux system, you must 

explicitly specify the board ID numbers by 

setting SW1 on each board to a different position 

(0-9 or A-F). Refer to the Configuration Guide for 

DM3 architecture products in your Dialogic

®

 

System Software documentation for further 

information about the board ID numbers. 

If you are connecting multiple boards via a CT Bus 

cable, the bus signal should be terminated on the 

boards that are located at the ends of the CT Bus 

cable. All other boards should be left in their 

factory default configuration with the CT Bus 

termination pins not linked.
To terminate the CT Bus, install a link clip over the 

pair of P5 pins indicated in the following figure. 

Each E1/T1 trunk on the DM/V1200BTEPEQ Media 

can be independently configured for front end 

loopback when the system is not powered up. As 

shipped from the factory, power-off loopback is 

enabled for all trunks. To disable power-off 

loopback on any trunk, remove the appropriate pair 

of jumper clips for the trunk as indicated in the 

Product Description section. 

The board’s loopback configuration during the 

boot-up interval (from power-on to completion of 

download) is set on a board-wide basis by jumper 

JP5. As shipped from the factory, the pins of JP5 

are not linked (the clip is installed over one pin 

only), enabling loopback during boot-up. To disable 

boot-up loopback, install the clip over both pins of 

JP5.
