Upgrading Software 3-3
Supervisory Port The supervisory port serves several functions by allowing the connection of
devices such as an 8100A Site Controller, modems, and terminal devices, however
it is recommended that the supervisory port be used with a terminal and/or modem
for configuring, status, and performance data gathering. The 8-pin modular RJ-48C
jack, as shown in Figure 3-1, provides direct terminal connections with the pinout
shown in Table 2-5 on page 2-4. For possible cable configurations, refer to
Figure 2-2 on page 2-4.
Received Loop
Codes
The PRISM 3002 responds to in-band loop codes received in ESF or D4 framing
mode and FDL loop codes received in ESF framing mode. Response to network
loop codes complies with TR54016 and T1.403 (1989) specifications. With either
line loopback (LLB) or payload loopback (PLB), the data from the DTE ports is
looped back to the DTE equipment. In a fractional V.54 loopback, the data port
does a bidirectional loopback.
Upgrading
Software The TEST and LOOP buttons can be used to set the SUPV port rate when
upgrading software for the 3002 (see page A-2).
