1.1 Standard Features
The FOCUS equipment offers the following
features as standard:
•Adc to dc isolated power supply for 24,
48/60, 110/125 or 250Vdc, 115 or 220 Vac
50/60Hz
•T1/E1 system supplying 24/30 DS0
channels for each of four T1/E1 ports
• Three output options:
• Electrical 1.544/2.048Mbps
• 1300 nm Laser
• 1550 nm Laser
• Sequence of events record
•Drop/Insert capability
• Loop operation
• Spur operation in conjunction with the loop
operation
•Six-port, (4 external) full 96/120 channel
DS0, non-blocking, full TSI cross connect
•Ability to connect loops together
• 100% software configured
• Remote Node Configuration, giving you
the ability to totally configure any terminal
in the system from any other terminal
The version Maintenance Module (with proper
framer and transceiver modules) determines
whether the system works as an E1 or T1 system.
MV2 & MV3 are T1 only systems. MV4 is an E1
only system. And MV5 may be configured for
either T1 or E1 systems, but not both simultane-
ously. Jumper J5, on the MV5 auxiliary board
(post 08/07), must be set for T1 or E1 (see Fig. 7-
10b). The PLOW LEDs (see Fig. 7-6) provide a
visual indication of the jumper position.
• T1 – PLOW Send/Receive LEDs are off in
both non-keyed & not equipped states.
• E1 – PLOW Send/Receive LEDs are on in
both non-keyed & not equipped states.
