Data Communications Channel (DCC) Provisioning 8
The DCC is automatically provisioned in the following manner and needs no
provisioning by the user. The DCC uses the SONET overhead to communicate
between NEs and follows the active SONET transmission line and/or IAO LAN.
In a given subnetwork, the NEs on each side of an optical span must have their
"user-side/network-side" (OSI terminology) parameters provisioned to opposite
values. Local procedures should determine the "user" and "network" side of a
span. For example, the CO terminal can be designated the network side and the
RT site the user side. It does not matter as long as the two sides are opposite
values. See the TOP section of this manual (Volume II) for OI provisioning
procedures.
■
In ring systems, there is one DCC assigned for the "m1" ring and another
DCC for the "m2" ring. The function unit slot pairs in ring systems have one
DCC each when connected to linear (1+1) OC-3 extensions.
■
In OC-1 ring applications when the function unit slot pairs are equipped
with 27G-U OLIUs, a DCC is assigned for each rotation of each OC-1 ring.
