Data Modules
21-65 The Modular Processor Data Module (MPDM)
21
General Features of the MPDM
Both the MPDM stand-alone and multiple mount versions are contained in a
70A Data Mounting aluminum housing that is equipped with plastic front and rear
covers.
The MPDM, in general, offers the following data features:
nSelecteddataratesupto64kbps
nSynchronous or asynchronous operation
nSynchronous operation at 56 kbps and 64 kbps
nFull- or half-duplex operation up to 56 kbps
nFull-duplex operation at 64 kbps
nAutomatic answer option
nACCUNET digital service interface support
nLocal Area Network (LAN) bridging: Token Rings, Ethernet, AppleLan
Functional elements
nThe Main module comes in one version that is common to all of the MPDM
packages and provides the basic digital interface and protocol conversion
functions.
nThe Interface module comes in three versions providing a choice of V.35,
RS-232-C, or RS-449 interfaces (balanced--RS-422A electrical interface).
nThe ACU module comes in one optional version. The ACU module
interface provides the capability to emulate an ACU and suppor ts the
RS-366 interface. This module is required for the data terminal dialing
function of the Data Call Setup feature.
Mounting
The MPDM can be configured either in a stand-alone or in a multiple mount
version. A maximum of eight MPDMs can be installed in the 71A Data Mounting.
The stand-alone version can be mounted on a surface or desk top near the
associated data equipment. The multiple-mounting carrier unit is normally
installed in an auxiliary cabinet.
Power
Both mounting arrangements require power from a 115-volt AC receptacle to
power the MPDM(s).

Switches
The MPDM is equipped with the following switches:
nORIGINATE/DISCONNECT — This switch is located on the front panel. It
is used when originating and disconnecting a call from a terminal that does
not have a BREAK key.
nSELF-TEST — This switch is located behind the front faceplate. It is used
to perform the self-test.
nLOC LOOP/REM LOOP — This switch is located behind the faceplate. It is
used to perform the Local loop test or Remote loop test.
NOTE:
If you are using the Video Teleconferencing MPDM or the High Speed
Synchronous MPDM preassembled package, and the OFF/ANET switch is
set to ANET), the user-activated Remote Loop will not function since
Remote Loop requires Mode 2 handshake operation.
nOptions — The option switches are located behind the front faceplate.
There are two Dual In-line Package (DIP) option switches, one with
10 positions, the other with 12 positions. Twenty-one of the positions are
used to set the options. The other is a spare reserved for future use.
The RS-232-C interface card has eight DIP switches to set its options.
Lights
The MPDM is equipped with the following lights:

Features of the AUDIX/CMS MPDM Package
Functional Elements
This preassembled package consists of the following par ts:
nStand-alone housing
nModular PDM
nRS-232 interface card
nOption Switch Settings
Since the AUDIX/CMS MPDM is preassembled, you will need only to make the
connections to the PBX, and set the DIP switches. Use the following table to verify
that the DIP switch settings connected to AUDIX or CMS are correctly set.

Features of the Video Teleconferencing MPDM
Functional Elements
The preassembled Video Teleconferencing MPDM consists of the following parts:.
nStand-alone housing
nModular PDM
nV.35 interface card
nRS-366 ACU interface card
nV.35 M1 (ACCUNET D-Kit)
NOTE:
The label on the front of this MPDM renames the data module from “MPDM”
to “MPDM ACCUNET.”
Option Settings
The Video Teleconferencing MPDM offers a new option switch, OFF/ANET.
nIf this switch is set to OFF, the MPDM/ACCUNET functions as a standard
MPDM.
nIf this switch is set to ANET, the Video Teleconferencing MPDM can be
optioned for compatibility with ACCUNET Switched 56 kbps Digital Service
or non-MPDM endpoints such as a DSU. In this mode:
— No Mode 2 handshaking is required to go into data mode
— Keyboard dialing is not supported
— User activated remote loopback test is not suppor ted
The baud rate depends on the setting of the speed option switches. When using
ACCUNET Switched 56 kbps Digital Service, the OFF/56K must be set to 56K. All
other speed switches must be set to OFF.
NOTE:
Only one speed selection is allowed when the OFF/ANET switch is set to
ANET.

Features of the High Speed Synchronous MPDM
Optional Interface Cards
There are two optional interface cards can be used with this MPDM package:
nV. 3 5
— Normal DTR operation
— Endpoint controls (asserts) the DTR lead
nV. 3 5 D T R
— DTR lead on the MPDM is always high
— Endpoint has no control over the DTR lead
— Call is typically under PBX control, for example, permanent switched
call (a DEFINITY G1 and G3) or dedicated switched call (a
DEFINITY G2)
Functional Elements
The preassembled High Speed Synchronous MPDM consists of the following
par ts:
nStand-alone housing
nModular PDM
nV.35 M1 * (ACCUNET D-Kit)
NOTE:
On the front panel the data module is renamed from “MPDM” to “MPDM
ACCUNET.”
Optional Settings
A new option switch, OFF/ANET, has been added, allowing the High Speed
Synchronous MPDM to be optioned in two different ways:
nWhen the OFF/ANET switch is set to OFF, this MPDM can be optioned to
function as a standard MPDM
nWhen the OFF/ANET switch is set to ANET, this MPDM can be optioned to
be compatible with ACCUNET Switched 56 kbps Digital Service. (Set
OFF/ANET to ANET for Dedicated Switch Call [DSC] arrangements.)
— No Mode 2 handshaking required to go into data mode
— Keyboard dialing is not supported
— Remote loopback test is not supported

21
The baud rate depends on the setting of the speed option switches. When using
ACCUNET Switched 56 kbps Digital Service, OFF/56K must be set to 56K. All
other speed switches must be set to OFF.
NOTE:
Only one speed selection is allowed when the OFF/ANET switch is set to
ANET.
When FDX/HDX is set to HDX (half-duplex), it can be used only on a 64 kbps
facility, such as alternate voice/data trunk, PRI facility, or switched-64. (The speed
can be set to 56 kbps, but requires a 64 kbps facility for proper HDX operation.)
REM/LOOP does not function when the OFF/ANET switch is set to ANET since
Remote Loop requires Mode 2 handshake operation.

The MTDM can be configured to support the Data Call Setup, Modem Pooling, or
Off-Premises Data-Only Extensions features. In addition to the standard data
transmission rates supported by previous versions of the TDM (0.3, 1.2, 2.4, 4.8,
9.6, and 19.2 kbps), the MTDM supports data rates of 56 and 64 kbps for
downloading and other high speed data transfer requirements.
