When requested to call a specific IMN, LES
translates the IMN to a Terminal ID.
The request is then sent to the MES which
translates the Terminal ID to an MSN number.
To "connect" a Terminal ID to a physical line,
FELCOM 50 incorporates a translation table.
This table can contain up to 100 ID translations,
and each Terminal ID in use is programmed with
type of call and destination.
A call is not allowed to be routed to a device that
is configured to another type than the Terminal ID
specifies. A telephone Terminal ID can only be
routed to a phone type device. A telefax Terminal
ID can only be routed to a fax device.
