3-4 O PERATION
Supervisory
Port
This 6 -pin modular RS-232 supervisory jack provides direct terminal access for
controlling the CSU and gathering status and performance data. The stand-alone
unit has an additional rear panel SUPV port. The operation of each port connector
is identical, but both supervisory ports must not be connected at the same time.
A terminal may be connected to this port for external software control. A modem
may be connected for remote access. This port may also be used to connect the
EM8000 Element Manager or 8100A Site Controller into the network.
BERT
Pattern
Select
Rotary Switch S1 determines the BERT pattern sent when the Test switch is in the
FAR position. Table 3-1 shows the corresponding BERT test pattern sent when the
rotary switch is set to positions 0 through 5.
The Clear pattern passes the received data through the unit (alarm detection and reporting
is disabled while the test is active).
