SpectraLink 6100 MCU: Facility Preparation: SpectraLink 6000 System
Prepare Demarc Blocks
20
The MCU is connected to the existing telephone system using RJ-21
connections. An MCU is designed to operate with a specific interface
to the telephone system: two-wire digital or analog, or four-wire
digital. The number of demarcation blocks required for the system
depends on the number and type of interface modules to be installed.
Interface Type
Analog POTS
Universal Digital Interface
(Norstar, Meridian, Comdial,
Fujitsu, Inter-Tel, DEFINITY
two-wire, NEC, Rolm,
Toshiba)
Merlin Legend and
DEFINITY four-wire
Mitel (DNIC)
Panasonic (Universal two-
wire Auxiliary Digital)
Executone (Universal four-
wire Auxiliary Digital)
If the wiring between the SpectraLink 6100 MCU and the telephone
system leaves the building, consult your telephone system manual
for instructions on providing adequate lightning and other over-
current protection. All MCUs (except the SCA analog interface
MCU) are intended only for connection to the isolated side of an on-
premises PBX. The interfaces are intended to connect to digital
PBX ports that provide signals of 5Vp-p (max) AC component and
some PBXs provide a 48 V DC offset.
Based on the number and type of interfaces in the system, determine
the number of 25-pair cables required to connect line ports and Base
Stations to the demarcation blocks.
The diagrams that follow provide an overview of the connections.
