OC-12 DCC Assignment Inputs 8
The OC-12 DCC assignments must be specified and administered using the
following inputs
*
:
â– CONFIGURATION-Enter-Assignment-DCC: This input assigns a DCC
channel to a particular low-speed interface "command" slot. Or, (whenever
1+1 protection is used) to a pair of low-speed interface "command" slots.
The service command slot must be specified first and then the protection
command slot will be assigned automatically.
NOTE:
For Release 7.1, the DCC channel will only be assigned for 0x1 protected
links. The command slots are 1B, 3B, 5B and 7B.
The user must specify a single DCC (channel 1-8).
After the low-speed interface command slot and DCC channel (channel
1-8) are specified, the user must specify the orientation (
user
or
network
). If
the
user
orientation is specified at one end of the OC-12 DCC link, the
network
orientation must be specified at the other end of the OC-12 DCC
link.
An input requesting an OC-12 DCC assignment will be denied if one of the
following conditions is present:
— The specified slot is not equipped with an OC12 (1.3 STD) circuit
pack.
— TheTOHCTLslotisintheAUTOstate.
— The TOHCTL circuit pack has been removed.
— The TOHCTL circuit pack has failed.
An input requesting an OC-12 DCC assignment may be denied if an
automatic turnup test is running. During that part of the test cycle when the
DCC connections between the OC-12 (1.3 STD) and TOHCTL circuit
packs are being verified, an input requesting an OC-12 DCC assignment
will be denied.
The CONFIGURATION-Enter-Assignment-DCC input can also be used
to change the value (
user
or
network
) of the orientation parameter
associated with an existing OC-12 DCC assignment. This is accomplished
by reentering the same OC-12 DCC assignment with the new value for the
orientation parameter.
* The FT-2000 OC-48 Lightwave System is menu-driven and prompts the user to enter the
desired input.
