Wiring Constraints

System Wiring

■System within 5 feet of dedicated AC power outlet.

■System within 25 feet of the network interface.

■Telephones within 1000 cable feet (304.8 m) of all telephones except MLX telephones. MLX telephones within 3000 feet of control unit. IROBs if needed.

■Ground wire for the power supply cannot be over 10 feet.

■If the SMDR printer is over 50 feet from the control unit, use an Asynchronous Data unit (ADU).

■Back-to-back connection of the DS1 facility with another system’s facility is possible when the cable distance is less than 1300 feet.

■Telephone Wiring.

■Maximum cord length from an MLX telephone to a ISDN data module is 80 feet (24 m).

■Total length of cords between the KS22911-L2 or 406743419 power supply and the MLX telephone cannot be more than 50 feet.

■Do not replace the 2-foot. D8AC cord (packaged with the DSS) with a longer cord.

■Radio base of the MDW 9000 cordless telephone must be at least 25 feet from the control unit.

PC Connections

To use the DOS SPM or WinSPM software, you must install the software using the directions packaged with the software. Also, your PC must be connected to the MERLIN LEGEND System directly via a serial port on your PC, or you must connect to the MERLIN LEGEND internal modem using your PC’s modem:

■Direct Connection. A serial port on your PC is connected directly to the MERLIN LEGEND System programming jack— the lower modular RS-232 jack on the processor module.

■Internal Connection. You are using a modem (either connected to or built into your PC) that is connected to the MERLIN LEGEND System (for example, via an 012 T/R or 016 T/R module) to access the MERLIN LEGEND internal modem.

■External Connection. You are using a modem (either connected to or built into your PC) and using a dial-up connection to access the MERLIN LEGEND internal modem. The External Connection type requires use of the Remote Access feature to allow you to connect to the MERLIN LEGEND programming port without human intervention.

■Manual Connection. You are using a modem (either connected to or built into your PC) and using a dial-up connection to access the MERLIN LEGEND internal modem. The Manual Connection is used when you must reach MERLIN LEGEND programming port by placing a call to the site and the person that answers transfers your call to the programming port.
