Supervisory Port Connection

Supervisory
Port
Connection

The front panel supervisory port serves several
functions. A modem may be connected to the SUPV
port for remote access or use of the COA (call on
alarm) feature. For cabling convenience, the
supervisory port may be used to connect the element
manager into the 3001 network (refer to NMS
Connection on page 2 -10
).

The supervisory port bit rate is set by configuration
Switch S6. The port is a serial RS-232 DCE port
configured for 8 bits, no parity, and 1 stop bit. The
physical connection is a 6-pin modular jack with the
pinout shown in Table 2-8.

High-speed
Port
Connection

The high-speed port connection [on the rear panel of both the stand-alone
(Figure 2-6) and the chassis unit (Figure 2-11)] utilizes a female subminiature
DB-25 connector. If the unit is connected to an EIA-530 DTE-type device, a
one-to-one DB-25 cable is all that is needed. If the unit is connected to an
RS449-compatible interface, an adapter cable must be used to match the 37 -pin
RS-449 standard. The V.35 option also requires an appropriate adapter cable to
connect to devices that use the standard 34-pin V.35 interface. Pin functions for
the high-speed port interface are listed in Table 2-9.
