ACCESS components
Introduction
There are three primary components on each side of the
Integrated Communication Link (ICL). They are briefly
discussed in the following sections. If you require a more
detailed description, refer to the Overview in the Meridian
ACCESS Configuration Guide (NTP 555-7001-315).
Meridian Mail
components
Toolkit (TK)
There is a Toolkit for each voice port on the system. The Toolkit
is responsible for executing API commands received across the
Meridian Integrated Communication Link (ICL).
Toolkit Master (TKM)
The Toolkit Master acts as a resource manager for Toolkit tasks.
There is a Toolkit Master for each node configured to have a
Meridian ICL.
Toolkit Communications (TC)
The Toolkit Communications task is responsible for driving the
Meridian ICL. It implements a proprietary protocol that
supports variable size packets, checksum error handling, virtual
channels, and retransmission on errors. Valid command packets
received are passed on to the appropriate toolkit task. There is a
TC for each node configured to have a Meridian ICL.
Application processor
components
Integrated Communication Link (ICL)
This task provides functionality equivalent to the Toolkit
Communications task for the applications processor side. The
link handler is split into two tasks: one receives data and the
other handles the output.
ACCESS Application Programming Interface (API) library
This is the ICL object code library containing ACCESS API
procedures that are linked in with the applications. Most
procedures translate into commands that are put into a data
packet and passed on to the link handler.
