Inbound Modem Pooling - Nortel QMT7 ADM Manual

The Ring Again queuing feature can also be applied by data callers who
encounter a busy modem pool at the time of dialing (see "Ring Again" on
page 52).
Provision The DDN and hunt group of the ADM/modem pair are entered in
the office data using LD 11.
Declaration of the VFDN is made in the office data using Overlay Program 10.
The number of pooled modems to be supplied is determined according to
customer utilization requirements, calculated by using Meridian Data
Features: Traffic Engineering and Configuration (553-2731-151). Modem
pools must be organized according to types and transmission modes (no
mixing is allowed).
Limitations Data calls placed through the modem pool over unconditioned
voice-grade lines are limited to a maximum transmission rate determined by
the modem capability or by the limitations of the unconditioned line.

Inbound Modem Pooling

Description This feature is only applicable to the QMT8 and higher
numbered ADM.
Each pooled modem consists of a QPC60 connected to a modem. The modem
is in turn connected to a stand-alone ADM. The ADM is connected to a DLC
in the SL-1 PE.
An inbound modem pool is a group of modems configured in a pool to permit
remote terminals to access local computer ports (or terminals) over a
voice-grade network. Both asynchronous and synchronous modems are
supported for access to single hosts. However, only asynchronous modems
are supported for access to multiple hosts. The Inbound Modem Pool is
separate from the Outbound Modem Pool. The dialing procedures are
different for access to a single host (via Hotline) versus access to multiple
hosts.
Note: With AMP there is no need to separate the inbound from the
outbound pool.
