Printer Connections; Smdi Connection (Optional) - Motorola McIAS 1610 Series System Manual

2.6.3 Printer Connections (optional)
For the McIAS 1610/IP, a parallel printer may be connected to the parallel port
located on the McIAS backplane; for the McIAS 1610/68, a serial printer may be
connected to either serial port "P3" or "P4". Refer to Table 1-2 for information about

printer connections.

2.6.4 SMDI Connection (optional)

Use the serial port labeled "P3" or "P4" to connect the SMDI link to McIAS if the
SMDI option is installed.
The Simplified Message Desk Interface (SMDI) is an analog interface between the
local Stored Program Control (SPC) switching system and the McIAS. Over this
interface, the SPC switching system provides information to the Cognitronics Voice
Mail system running on the McIAS about calls terminated to a set of associated lines.
The SPC switching system also receives requests from the Cognitronics Voice Mail
system to control Message Waiting Indicators for Voice Mail subscribers. A Message
Waiting Indicator can be a lamp on the telephone that is turned on to indicate a
message pending or the presence of a "stutter" dialtone heard by the residential
subscriber when the telephone is picked up.
Cognitronics' Voice Mail for Residential Subscribers (VM/R) AppSOFT Module adheres
to the Bellcore specification, "Simplified Message Desk Interface", Generic
Requirements, TR-NWT-000283, Issue 2, May 1991.
The SMDI interface can also be used in the EASM 1.0 AppSOFT Module to provide
out-of-band signaling for Changed Number Intercept (CNI) and Automatic Number
Announcement (ANA) calls.
