T1 Carrier Link Compatibility

MCR requires standard DSX-1 Interface (B8ZS clear channel). MCR will
support D4 or ESF framing protocols. Channel Service Units (CSUs) will be
required at the host and remote sites for each T1 carrier link. These units are
customer-provided (in some cases CSUs are supplied by the T1 providers).
The CSU must be configured for no robbed bit signaling. If a portion of the
twenty-four channels of the first T1 carrier link are used, the remaining
channels can be used with "drop-and-insert" channel banks. Standard T1 test
equipment is compatible with MCR because the design supports standard
Pulse Code Modulation (PCM) in standard T1 time slots.
Note: Mini-Carrier Remote is not intended for direct connection to the
Public Switched Telephone Network or other exposed plant networks.
Always connect this product to such networks through a certified (by
local, regional, or national safety agency and telecommunications
authority), isolating-type network terminating device (CSU, DSU, NTI,
NCTE, etc.) that provides overvoltage protection.
Analog 500/2500 sets are supported in Normal Mode operation. Analog sets
are not supported in ESAM operation.
