AT&T MERLIN LEGEND Release 3.1 System Programming Manual page 67

Product Enhancements
The Call Type field and the Called Number field on the SMDR report have
been changed for both the Basic and ISDN report formats.
An 012 port that is programmed as a generic voice messaging interface
(VMI) port can transfer an outside call to an outside number.
In a system where the transfer audible option is programmed for Music
On Hold and a music source is provided, outside callers who are
transferred to a calling group and are waiting in the queue or who are
parked or camped-on, hear music while they are waiting. Internal callers
never hear music on hold while waiting in the calling group queue or when
they are parked, camped-on, or being transferred to another extension.
Installation and Hardware
Installation and hardware enhancements include the following:
The control unit covers for the MERLIN LEGEND Communications System
are the same easy-to-use covers as those for the MERLIN II
Communications System.
A new 012 (T/R) module [apparatus code 517G13 (28) or higher letter]
contains a built-in ring generator. The maximum ring equivalency number
(REN) supported is 2.2, and the module will ring four ports at one time.
Bridging of single-line telephones is not supported due to poor
transmission quality.
A new 008 OPT module (labeled "with RING GEN.") contains a built-in
ring generator. It rings four ports at a time.
Ferrite cores for the power supply modules are shipped from the factory
to comply with FCC Part 15 requirements.
