Mini-Carrier Remote Fundamentals
Caution:
For proper operation of the Mini-Carrier equipment, the following settings
should be verified:
• Line build-out switches are set to accommodate a cable length that
corresponds to the approximate length to the CSU
• CSU is configured for the same framing format as the MCR (D4 or ESF)
• CSU is NOT configured for robbed-bit signaling
• CSU accepts B8ZS zero-substitution codes
Unused carrier links should be configured as "unequipped" (using the set
configuration command from the Man Machine interface terminal), to avoid a
constant alarm condition. The alarm relay contacts will remain active during such
an alarm condition.
assembly. See Figure 8: Cabling for a single Local Mini-carrier Interface card
(LMI) on page 45 for an illustration of the cable connections necessary for a single
LMI system. For an illustration of the cable connections necessary to daisy chain
the LMI's terminal connection, see
cards (LMIs) in a daisy chain
a. For single-LMI systems, SW2 positions 7 and 8 are OFF. See
LMI SW2 at U23 functions
b. For daisy-chained systems, the LMI connected to the terminal should
have SW2 position 7 OFF and SW2 position 8 ON. The LMI connected
to the SDI port should have SW2 position 8 OFF and SW2 position 7 ON.
The LMIs in the middle of the daisy chain, those not on the MMI end or
the SDI end, should have SW2, positions 7 and 8 ON. See MMI end and
SDI end and
instructions on how to properly set DIP switches for daisy chaining.
