Part number 613-10787-00

OmniConnect/ISDN (ST) allows a total of 8 ISDN devices to be connected together using the

S/T bus. The S/T bus requires 100-ohm terminations on both ends of the bus.

Note: The OmniConnect/ISDN is pre-configured without the100-ohm terminations. If the

terminator must be changed, please contact technical support for guidance.

h WARNINGS!

The ISDN jack is to be used for connection to ISDN equipment and lines only. The

connection of a standard phone line or an Ethernet 10Base-T line to the ISDN line may

result in severe damage. The 10Base-T, external POTS and ISDN cables look very much

alike. Care must be used to ensure the correct cable is being utilized.

OmniConnect/ISDN (ST) access devices must not be connected to the ISDN line under

any circumstances.

4.3. Ethernet (10Base-T) connections

Four 10Base-T (Ethernet) twisted-pair connectors on the OmniConnect/ISDN are used to

connect the unit to an Ethernet LAN. Other types of Ethernet cabling (AUI, 10Base-2, etc.)

are also supported through the use of an external converter.

To connect the OmniConnect/ISDN access device to a host computer (Windows or other PC

with an Ethernet or 10Base-T adapter), use the straight through RJ-45 cable provided.

Connections from the OmniConnect/ISDN to repeaters are supported without the use of a

crossover cable. The MDI switch located at the bottom of the access device may be used

switched to the ON position to perform the crossover function internally.
