Connect the MCI Line to the Switch
Connect the MCI Line to the Switch
The customer or the customer’s switch technician must complete this task. AT&T
does not assume responsibility for any cable connections to the NEAX 2400
switch.
The NEAX 2400 switch communicates with the SID through a Message Center
Interface (MCI) link. To connect the link, the customer must provide a cable to
connect to the MCI digital port and also provide an A25B cable to connect to the
MCI cable. Figure 4-2 shows all of the cables and connections required for the
integration.

Electronics Industry of America (EIA) RS-232 standard cable length of 50
feet.
