CAUTION:
No service DS1
LOW SPEED
slots should be left empty in a
group equipped with
MXRVO
and protection
HDSL
circuit
packs.
DLP-564If a new HDSL circuit pack is being installed, remove 177A
Retainer Card from DS1 slot being equipped, then set option
switches and install new HDSL circuit pack.
4. At each HDSL terminating node, use the set-t1: command to
set the characteristics of the DS1 port being established, if not
already performed.
5. At each HDSL terminating node, make the appropriate cable
connection(s) to the cross-connect point(s) or equivalent
connection point(s) for the circuit(s) being added.
6. Verify that no LEDs or alarms are activated. If any LEDs or alarms
are activated, refer to Trouble Clearing: IXL-001 and follow the
appropriate trouble-clearing procedure.
7.
NOTE:
Ring releases support only manual VT1.5 and STS-1
cross-connections. Manual STS-1 and/or DS1
cross-connections have to be made at each shelf to
configure the transmission path for each DS1 circuit being
established. Either terminating (drop) cross-connections or
"drop and continue" cross-connections are made at
terminating nodes and pass-through cross-connections are
made at intermediate nodes.
