• Remote Terminal to Local Device applications involve the use of an
inbound modem pool for incoming calls to access local devices
(terminals or computer ports). The Meridian 1 permits incoming data
calling on facilities also used for voice communications, such as WATS,
FX and TIE lines. (Figure 4).
Note: Remote Peripheral Equipment (RPE) may also be used for remote
terminals to local device operation. The various data applications and
hardware that may be connected to the Meridian 1 are shown in Figure 5.
The modem pool configuration provides internal data stations access to
shared dial-up modems for outgoing trunk calls or remote terminals access to
local computer ports over a voice grade network. An Add-on Data Module
(ADM) connected to the modem provides the Data Directory Number (DDN)
required for the receipt of incoming calls to the pooled modem.
Automated Modem Pooling
Meridian 1 offices that use X11 release 5 provide the database to
accommodate ADM Trunk Group and the optional Automated Modem
Pooling (AMP) features. These features allow access to local or remote data
stations using ADM/Modem pairs with a single-step dialing procedure and
eliminate the need for separate inbound and outbound pools. AMP uses the
Dataport Hunting feature to select the appropriate data set or dataport.
