WIRING

Each module T1 port uses a single RJ-48C jack to connect to a T1 circuit. Table 2-1shows the T1 pinout connection. The required wiring connection follows:

Connector Type		(USOC) RJ-48C
			Table 2-1. T1 Pinout Connection

PIN	NAME		DESCRIPTION

1	R1 RXDATA		Receive data from the network ring
2	T1 RXDATA		Receive data from the network tip
3, 6, 7, 8	Unused		n/ a
4	R TXDATA		Send data towards the network ring
5	T TXDATA		Send data towards the network tip

The HSSI/V.35 interface uses a single SCSI-II 50 pin connector with an op- tional V.35 adapter cable. Table 2-2 shows the SCSI-II connector pinout.
