Modular components allow easy, cost-effective growth in both
size and function. For upgrades from the MERLIN LEGEND
Communications System, all wiring and analog MERLIN system
telephones can be reused. For upgrades from the MERLIN II
Communications System, certain trunk and extension modules can
also be reused. The modules are 800, 400 (LS), 400EM, 012 T/R,
008, and 408.
Menu-driven system programming maintains the customer’s
command of business operations.
Built-in 1200/2400-bps modem allows fast access to the system
by customers, Lucent Technologies personnel, or authorized
dealers from a remote location for system programming and
maintenance.
Flexible mode of operation saves upgrade costs by allowing
system configuration in one of three modes: Hybrid/PBX, Key, and
Behind Switch. (The factory setting on the 3.0 processor board is
Hybrid/PBX.)
Connectivity to other systems in the Behind Switch mode
optimizes existing resources by allowing the system to work as part
of another MERLIN LEGEND Communications System,
System 25, System 75, System 85, DEFINITY 75/85, or other
communications system. The control unit can connect to another
system’s control unit via either an off-premises telephone (OPT)
line or an analog or digital tie trunk.
Digital 2.048-MHz bus supplies a 64-kbps channel on each of the
216 time slots.
68EC020 Motorola CPU running at 16 MHz with zero wait states
provides fast system performance.
Memory data retention saves time by ensuring that system and
extension programming information is retained for 5 days,
depending on the system configuration, in case of power failure or
system shutdown.
Integrated voice and data capabilities allow users to talk while
transmitting data at speeds up to 64 kbps.
DS1 interface can be configured for connection of either T1 or PRI
for basic call control with the 4ESS or 5ESS PRI service
specifications.
Basic Rate interface (BRI) S/T protocol supports premier digital
multiline (MLX) telephones with superior display capabilities and
supports the ISDN terminal adapter Data Module for the connection
of adjuncts.
