Connector Function
CONTROL A DB25 connector for a VT100 or equivalent terminal for a basic terminal
connection using command line interface commands. You can also connect 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
CWM Network Management; the LAN connector is used for CWM 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 CWM NMS. A terminal or
NMS other than CWM can also be connected to the BPX switch LAN port via
Ethernet. However, only the CWM NMS provides full management configuration
and statistics capabilities through 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 jumper 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.
