face, however, only SDCC is used for transparent DCC support.
7. Turin Networks Section DCC and transparent Section DCCs can coexist on the same optical
interface. The Turin Networks Section DCC will utilize the SDCC within the first STS of the OC-
n signal. This will reduce the number of transparent SDCCs slots available for that OC-n interface
by one.
8. Connections are limited to the first 64 timeslots and only up to 168 transparent overhead con-
nections.
9. DCC for EC1 STS1 cannot be cross-connected.
10.The TE-2020 cross-connects management traffic on a first come first serve basis, so the man-
agement bytes are not predefined.
3.13.3 Release 4.0 Transparent DCC Changes
Total Number of Transparent Connections (Per Node):
The total number of transparent overhead channels supported per node will increase from 40 to 64. Each
node should support 64 transparent SDCC channels and 64 transparent K1K2 channels. The SDCC chan-
nels should be independent of the K1K2 channels.
HS-PLM SDCC:
The maximum number of transparent SDCC channels per HS-PLM will decrease from 64 to 32. (This
will free up 64 SDCC channels)
HS-PLM K1K2:
The maximum number of transparent K1K2 channels per HS-PLM will remain at 32.
SFF PLM SDCC and K1K2:
The maximum number of transparent DCC and transparent K1K2 byte channels per SFF PLM will
remain at 32.
LEI SDCC:
16 transparent SDCC channels will be added to each LEI (i.e. LEI #1 thru #4).
LEI K1K2:
16 transparent K1K2 channels will be added to LEIs #1, #2, and #3, while 15 transparent K1K2 channels
will be added to LEI #4.
LEI K1K2 Transport::
McBain/McBasic will pass the K1K2 bytes transparently over the LEI using the D4 and D5 bytes
(LDCC) in LEI STS-48 channels 33 through 48. LEI STS-48 channel 33 will be fixed mapped to the 1st
LEI K1K2 channel; LEI STS-48 channel 34 will be fixed mapped to the 2nd LEI K1K2 channel; etc.
