Function
CONTROL A DB25 connector for a VT100 or equivalent terminal for a
basic terminal connection using command line interface
commands. Can also be connected to a dial-in modem for
remote service support or other network management dial-up
access. This is a bidirectional RS232 communications port.
This is not used for SV+ Network Management; the LAN
connector is used for SV+ Network Management.
AUXILIARY A DB25 connector for a system printer. This is a one-way,
RS232 outgoing port.
LAN A DB15 Ethernet LAN connection for connecting to a
StrataView Plus NMS. A terminal or NMS other than SV+ can
also be connected to the BPX switch LAN port via Ethernet.
However, only the SV+ NMS provides full management
configuration and statistics capabilities via SNMP and TFTP.
EXT TMG A 75-ohm BNC connection for clock input. An E1 source with
75 ohm impedance typically uses this connector. If the shield
on the cable needs grounding, slide the BCC back card out and
jumped connector JP1 across its two pins.
EXT 1 TMG DB15 connector for a primary and optional redundant external
source of system clock. A T1 source with 100 ohm impedance
or an E1 source with 100/120 ohm impedance typically use this
connector.
EXT 2 TMG Provides for an external clock source redundant to the EXT 1
TMG source.
