OC-3/OC-12 Path Switched Ring (0x1)

9

A DDM-2000 OC-3 ring shelf can function in a ring-on-ring application using the
0x1 interface capability of the OC-12 or FT-2000 OC-48 Lightwave System ring.
The OC-3 shelf functions in the normal path switched ring mode. VT/STS path
protection switching is done on the OC-3 shelf as previously described for an
OC-3 ring.

In single homing, the OC-3 ring shelf interconnects through its main-1/main-2 ring
interface either directly or through another OC-3 ring shelf to the low-speed OC-3
0x1 interface on a single OC-12 or FT-2000 OC-48 Lightwave System shelf.

In dual homing, the OC-3 ring shelf interconnects directly or through another OC-3
ring shelf with the OC-3 interfaces on two separate and normally non-colocated
OC-12 or FT-2000 OC-48 Lightwave System shelves.

OC-3/OC-1 Path Switched Ring (0x1)

9

The OC-3/OC-1 path switched ring is similar to the OC-3/OC-12 ring-on-ring. A
DDM-2000 FiberReach shelf interconnects with a DDM-2000 OC-3 ring host shelf
through low-speed OC-1 interfaces on the OC-3 ring shelf. VT/STS path
protection switching is done on the DDM-2000 FiberReach shelf.

In single homing, the DDM-2000 FiberReach ring interconnects through a pair of
low-speed OC-1 0x1 interfaces on the OC-3 shelf.

In dual homing, the OC-1 ring interconnects through the low-speed OC-1 0x1
interfaces on two separate and normally non-colocated OC-3 shelves.

Status of ACTIVE LED on Rings

9

In all ring applications, ACTIVE LEDs on each main OLIU are always lit because it
is not known if a signal on that OLIU is currently being selected by a far-end NE.

Equipment Protection

9

The DS3, MXRVO, STS1E, and TG circuit packs are 1

×

1 protected and use

nonrevertive switching. Green ACTIVE LEDs are provided on the faceplates of
these circuit packs to indicate which ones are active (carrying service).

The DS1 circuit packs are 1

×

7 protected and use revertive switching. To prevent

frequent protection switches caused by intermittent failures of a DS1 circuit pack,
the system provides an "automatic lock" feature. If four automatic protection
switches are done on the same DS1 circuit pack within a 10-minute interval, traffic
