MERLIN LEGEND Communications System Release 6.1
Feature Reference 555-661-110
Features
Uniform Dial Plan Features
In Release 6.0 and later systems, T1 channels can be programmed either to
emulate voice tie trunks or data tie trunks. These can be used as tandem trunks
linking networked systems. In addition, you can use drop-and-insert equipment to
supply fractional T1 use; see the Network Reference for more information.
Telephone Differences
Queued Call Consoles
For Release 6.0 and earlier systems, an extension may not have its calls covered
by a QCC on another system. In Release 6.1 and later systems (Hybrid/PBX
mode only), a QCC can be the non-local extension that is the single non-local
member in a calling group.
A QCC operator can manually extend an outside or non-local dial plan extension
call to a local extension, non-local dial plan extension, or a destination outside the
private network. If the destination is a non-local extension and the call extending
(Join) is completed to a busy or invalid number, the transfer can be returned only if
the Join took place over tandem PRI trunks. If the Join took place over tandem tie
trunks, it is not returned in the event that the destination is busy or invalid.
A QCC Pool Status button shows activity on private network trunk pools as well
as on other trunk pools.
A call from a non-local dial plan extension over tandem tie trunks is prioritized as
an outside call to the QCC and treated as an outside call for the purpose of the
Join function.
Direct-Line Consoles
To prevent toll fraud, private trunks should not be assigned as personal lines on a
DLC, nor should a DLC be given dial access to private trunk pools.
Direct Station Selectors
In Release 6.0 and earlier systems, DSS buttons function only for local system
extensions. In Release 6.1 and later systems (Hybrid/PBX mode only), DSS
buttons can be pressed for non-local extensions. However, no busy indications
appear on the DSS for non-local extensions.
Single-Line Telephones
In Release 6.0 and later systems, single-line telephones can perform the same
trunk-to-trunk transfers as other extensions, even though they are prohibited from
making trunk-to-trunk transfers of inside or outside calls to local system trunks.
