Connecting Cables from the
Platform to the Switch
To begin switch connections from the MAP platform, you must connect to the GP
Synch circuit card which is located in slot 1 on the MAP/5. Verify the slot location.
The GP Synch card has a single 25-pin RS-232 connector on the faceplate.
Using an IDI or MPDM for Switch Connections
Connections from the platform to the switch must be made through either an IDI
(isolating data device) or an MPDM (data module). Direct connections to the
switch are not allowed.
An IDI functions as a ground device (RS-449). The cable is RS-232 on one end
for connection to the GP Synch circuit card and RS-449 on the other end for
connection to the IDI.
The MPDM provides a digital port connection to the switch from the GP Synch
circuit card. You must use an MPDM in the following situations:
■
The connection from the platform to the switch is greater than 400 feet
(122 meters).
■
The switch to which you are connecting has duplicated common control.
■
The switch has DC power.
The last two items do
not
apply to DEFINITY G3r or G2 and System 85 R2V4.
See the following illustration for an overview of the types of connections that need
to be made from the MAP platforms to various Lucent switches.
