ON/OFF Switch
This switch provides AC power to the MultiMux when placed in the On (UP) position and removes power when in the OFF (down) position.
Power Connector
The power connector is a receptacle for the
CHANNEL 1-16, CHANNEL 1-32
Channel 1 through channel 16 or channel 1 through 32, depending on MultiMux model, are used to connect the async devices. These connectors provide the RS232C connection.
2400 BPS MODEM DIAL-UP LINE Connector
This connector is used when the command modem is connected to a separate
COMMAND PORT TERMINAL/PC Connector
The command port terminal/pc connector is used to connect the supervisory console to the MultiMux. The supervisory console can be either an ASCII terminal or a pc with a serial port running communications software. The command port connector has a DCE physical interface with a DB25 female connector.
COMPOSITE LINK A INTERNAL DSU Connector
The composite link A internal DSU connector is used to connect the internal DSU on link A to the DDS or dedicated network . This connector provides an RJ48 connection.
COMPOSITE LINK A EXTERNAL MODEM/DSU Connector
The composite link A external modem/DSU connector is used when either a compatible external composite link modem or external DSU is connected to the MultiMux. This connection can be either RS232C or V.35. If the connection is V.35, then the composite link A shunt on the aggregate board must be moved from the RS232C (default) position to the V.35 position. This connector is a DB25 female connection.
COMPOSITE LINK B INTERNAL DSU Connector
The composite link B internal DSU connector is used to connect the internal DSU on link B to the DDS or dedicated network . This connector provides an RJ48 connection.
COMPOSITE LINK B EXTERNAL MODEM/DSU Connector
The composite link B external modem/DSU connector is used when either a compatible external composite link modem or DSU is connected to the MultiMux or the connection is used to connect a synchronous device. This connection can be either RS232C or V.35. If the connection is V.35, then the composite link B shunt on the aggregate board must be moved from the RS232C (default) position to the V.35 position. This connector is a DB25 male connection.
