Connectors and cables

TX 5000E boards have two Dialogic® MD1 RJ-45 T1/E1 trunk interfaces and three Ethernet connectors. The following illustration shows these connectors on the TX 5000E board end bracket:

Dialogic® MD1 RJ-45 interface

TX 5000E boards provide Dialogic® MD1 RJ-45 interfaces to connect to a T1 or E1 network. The following illustration shows the Dialogic® MD1 RJ-45 pin assignments:

To access Trunk 1, Trunk 2, or both Trunks 1 and 2, connect a shielded T1 or E1 RJ-45 cable to one or both 8-pin modular jacks on the board.

Use dual T1/E1 120 ohm trunk adapter cables to connect Trunk 3 or Trunk 4 to the 8-pin modular jacks on the board. Each trunk adapter cable divides the 8-pin modular jack on the end bracket into two RJ-48C connectors. If you are connecting both jacks, use two cables, otherwise just use one. Connect the shielded RJ-45 cables directly to the trunk connector on the board or to the trunk adapter cable.

For more information about the trunk connections, refer to the Dialogic® NaturalAccess™ Signaling Software Configuration Manual.

Note: TX 5000E boards are configured as a T1/E1 120 ohm board. To connect a TX 5000E board as an E1 75 ohm board, use a balun transformer to convert the impedance from 120 ohm to 75 ohm. No other configuration changes are required.

Ethernet interfaces

TX 5000E boards have two 10/100/1000Base-T Ethernet interfaces and one 10/100Base-T Ethernet interface. These interfaces provide Ethernet connections that support auto-negotiation for full duplex/half duplex transmission. The Ethernet interfaces provide a high-speed interface for connecting a TX 5000E board to its redundant mate board. Refer to Connecting TX boards for redundancy for more information.

The following illustration shows an Ethernet interface:
