Single 0x1 Cross-Connection
In a dual-homed application, the DDM-2000 OC-3/OC-12 Multiplexer uses a single 0x1
cross-connection to map the VT1.5 channels between the DDM-2000 FiberReach OC-1
and the DDM-2000 OC-3/OC-12 rings. This single 0x1 architecture maps low speed to
high speed on a specified ring rotation. The high speed to low speed drop is made on the
same specified ring with no path switching. Protection is provided at the VT1.5 end
points. See Dual 0x1.
Single Homing
In DDM-2000 FiberReach, a network topology in which a single OC-3 shelf serves as a
DDM-2000 FiberReach Multiplexer host supporting up to six OC-1 rings. A
SLC-2000
Access System serving as a host can support up to two OC-1 rings. See Dual Homing.
Site ID
A switch settable parameter with values of from 1 to 8. Displayed on SYSCTL circuit pack
to indicate to which site the user panel alarms and LEDs apply.
SLIM
Subscriber Loop Interface Module
SM
Single Mode
SONET
Synchronous Optical NETwork
SPE
Synchronous Payload Envelope
SQU
Sync Quality Unknown. Used in synchronization messaging.
SRD
Software Release Description
Standby
Standby identifies a 1+1 protected OC-N line which is not currently selected by the
receiver at either end as the payload carrying signal, or a 1x1 or 1xn protected circuit
pack that is not currently carrying service. (See Active.)
Star Topology
For DDM-2000 FiberReach, this refers to a configuration of multiple point-to-point OC-1
extensions from a single DDM-2000 OC-3/OC-12 Multiplexer.
Status
The indication of a short-term change in the system.
STS, STS-n
Synchronous Transport Signal — The basic logical building block signal with a rate of
51.840 Mb/s for an STS-1 signal and a rate of n times 51.840 Mb/s for an STS-n signal.
