A Physical Installation

1. Place the SP201-SA on a tabletop or shelf.

2. Connect the cables for one set of trunks to the ports on the rear of the SP201-SA chassis, as follows:

a For the CAS trunk (DTMF, R1, R2, or N5), do one of the following:

◆ For DTMF or R1, connect a T1 cable to the RJ48C port labeled Port 1.

◆ For R2 or N5, connect an E1 cable in one of the following ways:

- Connect an E1 cable to the RJ48C port labeled Port 1.

- Connect an E1 cable to the BNC Rx and Tx ports labeled Port 1.

b For the ISDN trunk, do one of the following:

◆ For ETSI ISDN on a two-port SP201-SA, connect an E1 cable to the RJ48C port labeled Port 2.

(For ETSI ISDN on a four-port SP201-SA, connect an E1 cable to the RJ48C port labeled Port 3.)

◆ For NI2 ISDN on a two-port SP201-SA, connect a T1 cable to the RJ48C port labeled Port 2.
