System Introduction
Issue 3 June 2001 1-19
— STS-3c 0x1 Configuration. This application provides the ability of
transporting STS-3c services on OC-3c low speed FUNCTION
UNITS optical interfaces that have been provisioned for 0x1 with
29G-U/29H-U OLIUs in MAIN and 22-Type OLIUs in FUNCTION
UNITS slots. STS-3c routing is restricted to FUNCTION UNITS C.
— STS-1/VT1.5 0x1 Configuration. This application provides the ability
of transporting STS-1 services on OC-3 low speed FUNCTION
UNITS optical interfaces that have been provisioned for 0x1 with 29/
24/22-Type OLIUs in MAIN and 22-Type OLIUs in FUNCTION
UNITS slots of the host OC-3 shelf.
■
New Features:
— Support the OC-12 optics through the 29G-U/29H-U OLIU circuit
packs in the Main Unit slots. The related features are as follows.
■
STS-1/STS-3c/VT1.5 pass-through cross-connections on the
29G-U/29H-U OC-3 equipped shelves.
■
STS-1 and VT1-5 cross-connections between MAIN slots
equipped with the 29G-U/29H-U OLIU and FUNCTION
UNITS slots, providing a fully flexible assignment of VT and
STS-1 timeslots out of any of the 12 STS-1s that are
available on the 29-type OLIU.
■
In service upgrades to the new 29G-U/29H-U OLIU
— Stratum 3 timing generator circuit pack (BBF4). The TG3 operates
with an internal oscillator of
±
4.6 ppm long term accuracy.
— Support DCC provisioning on MAIN (identical/distinct) for OC-3/OC-
12 ring interface. An Identical DCC mode will allow a remote OC-3
shelf to interconnect through its MAIN ring interfaces with a 1+1
linear extension on a host OC-3, OC-12, or OC-48 shelf using ring
software.
— Support the provisioning of asynchronous CIT port to run TL1, as
well as the provisioning of the synchronous X.25 port to be used for
asynchronous TL1 interface.
— Remote alarm status (using the AGNE and the Alarm Group
concept)
— CPro-2000, ITM SNC support. Release 15.0 is supported by:
CPro-2000 Release 10.0; ITM SNC Release 10.0.
— Software download to upgrade BBF9 and BBF10 IMA LAN circuit
pack.
