Overview
The COMSPHERE
3600 Series Data Service Units
(DSUs), Models 3610 and 3611, support communication
between computers and other data processing devices by
providing connections to digital transmission facilities.
The 3600 Series DSUs can be optioned with hardware to
support the following capabilities:
•
Dial backup (point-to-point and multipoint).
•
LPDA-2 (Link Problem Determination Aid,
Release 2) interoperability.
•
Time Division Multiplexing (TDM).
•
Multichannel Multipoint (MCMP).
•
Digital bridge.
The time division multiplexing, multichannel
multipoint, digital bridge and multipoint backup
capabilities are discussed in this applications guide.
LPDA-2 interoperability, as it applies to applications
requiring installation of the TDM or MCMP option, is
also discussed in this guide.
The time division multiplexer (TDM) option, an
additional circuit card, supports time division
multiplexing and digital sharing for up to six ports. It can
serve as a digital bridge for multipoint dial backup and
multipoint local area data set (LADS) operation.
The multichannel multipoint (MCMP) option is a
circuit card that provides multipoint TDM capability. The
MCMP capability allows up to six independent
application programs to share one 56 kbps multipoint
circuit. Channel speeds can range from 1.2 to 48 kilobits
per second (kbps) and the sum of the speeds must be less
than or equal to 48 kbps.
The TDM can be software-defined to provide the TDM
or digital bridge capability; the MCMP option can be
software-defined to provide TDM, MCMP, or digital
bridge capability. However, only one of these capabilities
can be in effect at a time. The TDM cannot be upgraded to
support MCMP capability.
