The SN4830's X.21 interface is wired as a DTE, however, it can also be configured as a DCE. The SN4830's
X.21 interface requires a cable with a male DB-15 connector. Attach the male DB-15 connector of the X.21
cable to the female DB-15 connector on the SN4830. Attach the other end of the cable to the X.21 connector
on local modem or multiplexer device.
Installing the T1/E1 twisted pair cables. The T1/E1 is usually connected to a PBX or switch (local exchange
(LE)). Type and pin-outs of these devices vary depending on the manufacturer. In most cases, a straight-
through RJ-48C to RJ-48C can be used to connect to the T1/E1 (see for E1 RJ-48C pin-out listing) with a
PBX. A cross-over cable is required to connect to an NT1.
