Chapter 33 AT3-6ME (T3 to T2) Interface Adapter

Installation

Install the AT3-6ME in a rack adjacent to the BPX enclosure (allowing room for any AC Power Supply

Assembly that you might need to mount) wherever there is space for the AT3-6ME adapter.

System Connections

Two short BNC-BNC cables are required to connect the AT3-6ME to the BPX node.

Step 1 For use with BPX switch, connect one cable between one of the three TX connectors on a selected BPX

LM-3T3 card and the T3-RX connector on the AT3-6ME back panel.

Step 2 Connect the other cable between the associated RX connector on the BPX LM-3T3 or ATMT card and

the T3-TX connector on the AT3-6ME back panel.

Step 3 Connect the cable coming from the 6 Mbps facility to the T2-RX connector on the AT3-6ME.

Step 4 Connect the cable going to the 6 Mbps facility to the T2-TX connector on the AT3-6ME.

Step 5 Connect the AC power cord to the IEC connector on the rear of the AT3-6ME.

AT3-6ME Configuration

You configure the adapter by seting a group of DIP switches located on the front panel. There are two

sets of switches:

• a 12-position switch

• a two position switch.

This switch enables the configuration change via the terminal and enable/disable the loop push

button located in the front panel (to secure against accidental operation).

Review both Table 33-3 and Table 33-4. Set the appropriate DIP switches with the power off.
