Connecting these hardware components requires two (optionally three)
signaling links:
¥ is an Application Module Link (AML), which connects the
Link 0
Meridian 1 system to the IPE Module or the Application Module.
¥ is a Host Link (or Meridian Link), which connects the host
Link 1
computer to the IPE Module or the Application Module. This Host Link
can be implemented as a dedicated X.25 link supporting a single host
computer or as a TCP/IP Ethernet LAN link supporting as many as 16
Meridian Link applications.
Note 1: If both the Meridian Link (using TCP/IP) and CCR
applications are running, the Meridian Link third-party application can
support only up to 15 Meridian Link applications.
Note 2: Any mlusr administration sessions requiring association IDs
will reduce the number of association IDs available for Meridian Link
applications. For example, if your system has eight association IDs
registered to Meridian Link applications and then you register two
association IDs for mlusr administration, your system will have six
association IDs available (five, if CCR is running).
Note: If you have registered all 16 association IDs (15 if CCR is
running) to Meridian Link applications, two overflow association IDs
are available for mlusr administration only.
¥ is (optionally) a Meridian Mail Link (MML), which connects a
Link 2
Meridian Mail system to the IPE Module or the Application Module.
In addition, the IPE Module and the Application Module provide an
interface for a system console, which enables you to perform administration
and maintenance. A port that is designed to be connected to a modem
allows you to perform these activities from a remote location.
The key software required to make these hardware components and links
work together is the Meridian Link application, which resides in the IPE
Module or Application Module.
