IP asynchronous links
IP asynchronous links enable Communication Manager to transfer existing
asynchronous adjunct connectivity to an Ethernet (TCP/IP) environment. IP
asynchronous links support switch server applications, as well as client
applications. Systems running Communication Manager can connect to System
Management applications such as the Avaya Visibility Suite over the LAN. Call
Detail Recording (CDR) devices, Property Management System (PMS) and
printers can be connected using asynchronous TCP/IP links.
IP asynchronous links:
■ Reduce the cost of connecting to systems running Communication
Manager for various adjuncts
■ Allow for an open architecture to transport information and increases the
speed at which data is transferred
■ Allow customers to manage applications from on-site or remote locations
■ Allow several system management applications to run on a single PC,
thereby reducing hardware requirements
■ Guarantee data delivery through a reliable session-layer protocol
■ Support customers’ existing serial hardware investment through use of
Network Terminal Servers
Modem pooling
Enables switched connections between digital data endpoints (data modules) and
analog data endpoints and acoustic coupled modems. Data transmission between a
digital data endpoint and an analog endpoint requires a conversion since the DCP
format used by the data module is not compatible with the modulated signals of an
analog modem. A modem translates DCP format into modulated signals and vice
versa. The Modem Pooling feature provides a set of modems for such
conversions.
Communication Manager modem pools are assigned into modem pool groups. A
group can have up to 32 modems, called “members.” Communication Manager
can have as many as 63 modem pool groups. See Figure 5.
