Connect to Line Interface as follows:

1.Plug one end of the crossover RJ-48 cable into one of the eight WAN E1 or T1 ports on the rear of the tran- sition modules. This cable from Quintum would be the red RJ-48 crossover cable. See Chapter 2: Hard- ware Components for cable pinouts if you are making your own cables.

2.Connect the other end of the crossover RJ-48 cable into the appropriate port on the PBX. (If another cable or adapter is required, see Chapter 2: Hardware Components for RJ-48 crossover pinout information.

NOTE: If you are connecting to an external CSU, ensure the Digital Interface is configured as short haul (or DSX-1), otherwise, configure the Digital Interface to DS-1 to enable the built in CSU via Com- mand Line Interface (CLI). See Chapter 4: Getting Started with Command Line Interface (CLI).
