38-2: PSTN Fiber Group Properties
Parameter Name Type
Provisioning
Type
Description
Fiber Group
Name
String
Up to 20 chars
Instant Defines name of the PSTN Fiber Group
allowing user to easily identify it.
Interface Type
Enum
Unknown, STM1,
OC3
Offline Defines type of the Fiber Group Interface.
Protection Mode Enum
Unprotected,
Protected
Offline Defines the APS protection mode of the
Fiber Group.
Active Link Integer
1-2
Read-Only Indicates which of the Fiber Group links (A
or B) is currently active.
Revertive Mode Enum
Non-Revertive,
Revertive
Offline Defines revertive or non-revertive behavior
of the APS protection mode. In revertive
mode, when failed Link A returns to service,
activity is automatically switched back to it.
In non-revertive mode the activity remains
on Link B.
Wait-To-Restore
Delay (WTR)
Integer
5-13
Offline Defines delay time-out (in seconds) for
Wait-To-Restore feature.
APS Dir Mode Unidirectional,
Bidirectional
Offline Defines whether unidirectional or
bidirectional APS mode is used.
KLM Numbering
Scheme
Enum
ETSI, GR253,
Timeslots
Offline Defines the scheme for VC/VT numbering
inside STM-1/OC-3. Once a scheme is
selected, there is mapping of 3 numbers
(K,L,M) identifying VC/VT inside the STM-
1/OC-3 to an E1/T1 trunk number.
Mapping Type Enum
AsyncVT15ofDS1,
AsyncTU12ofE1,
STS1ofDS3
Offline Defines the SDH/SONET mapping type
(TU/VT/STS1 signal label + payload
mapping type).
 AsyncVT15ofDS1 – T1/VT1.5 mapper
for SONET
 AsyncTU12ofE1 – E1/TU12 mapper for
SDH
 STS1ofDS3 – T3/STS1 mapper for
SONET (channelized T3)
