NSTALLATION
The NMS address, port rate, and power
up configuration mode may be set by
either configuration switches or
through software control. The physical
connection is 6-pin modular connector
with the pinouts for these connectors
shown in Table 2-16. This port is a
serial RS-232 DCE port configured for
eight bits, no parity, and one stop bit.
Data Port
Connections
Both models of the
Verilink 1051 chassis
provide connection to the
customer equipment. Each
slot of the 1051-2 has a
corresponding DTE 8-pin
RJ-48 connector and a
high-speed DTE female
25-pin connector located
on the chassis rear panel.
The 1051-3 chassis is
similar except that it has a
high-speed DTE 34-pin
connector instead of the
25-pin connector. The
pinout for the DTE RJ-48
connector is given in
Table 2-17 and the pinout
for the high-speed DTE
connectors is given in
Table 2-18.
FCC rules require that interconnecting cables carrying high-speed data be shielded
appropriately to minimize radio frequency interference.
