Connecting the T1/E1 Digital

Voice Port

If your Cisco MC3810 has a T1/E1 digital voice

port, connect it to a digital PBX.

If the digital voice port has an RJ-48 jack, use an

RJ-48-to-RJ-48 rollover cable (not included), or a

special cable if required for your application.

Ifthe digital voiceport has BNCconnectors, use two

75-ohm coaxial cables with BNC connectors (not

included).

Note: For an RJ-48 connection to most PBXs, a

rollover cable isrequired. However, somePBXs may

have a connector pinoutfor a straight-through cable.

Step 1 For an RJ-48 cable—Connect one end of

the cable to the RJ-48 jack labeled T1/E1

on a tan background.

For coaxial cables—Connect one end of

the cables to the BNC connectors labeled

E1 on a tan background.

Note: Be sure to make the correct transmit and

receive connections for both 75-ohm cables.

Step 2 Connect the other end of the cable(s) to

the digital PBX.
