MERLIN LEGEND Communications System Release 6.1
Feature Reference 555-661-110
Features
Primary Rate Interface (PRI) and T1
Routing by Dial Plan (Release 2.0 and later). Routing by dial plan
supports call handling similar to DID. For example, you can specify that
calls received from a particular area code should be routed to a specific
person or group responsible for accounts in the area.
Routing by dial plan performs digit analysis on incoming calls, matches to
Called Party Numbers (CdPNs), and delivers the calls to the destinations
based on the respective Called Party Numbers. It also allows multiple calls
to the same directory number. That is, multiple concurrent incoming calls
with the same Called Party Number can be delivered to a destination
simultaneously.
Call-by-Call Service Selection (Release 2.0 and later). This feature
maximizes use of communications lines, providing more services with
fewer lines. Call-by-call service selection provides more than one PRI
service (such as VPN service and OUTWATS) for each B-channel. Based
on the number dialed and the bearer capability (voice, data, or both), the
system chooses which service is used. If a caller requests operator
service, the system bypasses call-by-call service selection.
Restriction Code Handling for FTS2000 Network (Release 2.0 and
later). FTS2000 network users can have restriction codes applied to their
extensions. A person who attempts to place a call that exceeds the set
restriction level must first enter a restriction code. If no code is entered, the
FTS2000 network prompts the user to enter the code from the telephone
dialpad. The system allows a restriction code to be entered with the
Account Code Entry feature. This is especially useful for data calls.
Networked Tandem PRI Trunks (Release 6.0 and later systems,
Hybrid/PBX mode only). Networked PRI trunks allow cost-effective use of
trunks by remote networked users, transparent dialing of extensions
connected to networked systems, shared automated attendant systems
under some conditions, and flexible display features for MLX display
telephones. PRI dial plan routing is not applied to calls received on tandem
PRI trunks. For additional information, see this section and
Plan Features" on page
T1
A DS1 facility programmed as a T1 line/trunk uses 24 channels, sometimes
referred to as DS0 channels , each with a capacity of 64 kbps. Signaling must be
in-band signaling, however, which limits the data rate for each channel to 56 kbps
when the channels are programmed for Switched 56.
NOTE:
The availability of the caller identification information may be limited
by local-serving (caller's) jurisdiction, availability, or service provider.
Blocking Caller ID is possible system-wide by accessing the PRI
Lines menu. For information, see System Programming , Chapter 3,
"Copy Telephone Number to Send".
