User's Manual 58. Configuration Parameters Reference
Table 58-59: SDH/SONET Parameters
Parameter Description
Transmission Type
[PSTNTransmissionType]
Defines the PSTN transmission type for the device.
 [0] None = (Default) PSTN Transmission type is not defined.
 [1] SONET/SDH = Optical SONET or SDH transmission type.
 [2] DS3 = Copper T3 transmission type.
Notes:
 For the parameter to take effect, a device reset is required.
 The parameter is applicable only if the TDMBusType parameter
is set to FRAMERS (2).
Mode
[SdhFbrGrp_SdhSonetMode]
Determines the SDH/SONET mode for the PSTN interface,
typically per Fiber Group.
 [0] UNKNOWN = Not defined
 [1] STM1 = STM-1
 [2] OC3 = OC-3
When STM-1 mode is selected, set the
SDHFbrGrp_Mapping_Type parameter to 1 (i.e., Asynchronous
TU12 and E1) and ProtocolType for E1. When OC-3 mode is
selected, set the SDHFbrGrp_Mapping_Type parameter to 0
(Asynchronous VT1.5), 2 (Byte-synchronous VT1.5), or 3
(Asynchronous mapping of DS3 in STS1), and ProtocolType for
DS1.
Notes:
 For the parameter to take effect, a device reset is required.
 The parameter is applicable only if the TDMBusType parameter
is set to acFRAMERS (2), PSTNTransmissionType is set to
SONET/SDH (1), and SdhFbrGrp_SdhSonetMode is not set to
UNKNOWN (0).
Mapping Type
[SDHFbrGrp_Mapping_Type]
Determines the SDH/SONET mapping type (signal label and
payload mapping type) for the PSTN interface. This is typically
selected per Fiber Group.
 [0] VT1.5 Asynchronous = Asynchronous VT1.5 and DS1 (for
OC-3).
 [1] TU-12 Asynchronous = Asynchronous TU12 and E1 (for
STM-1).
 [2] TU-11 Byte Synchronous = VT1.5 Byte Synchronous
mapping (for OC-3).
 [3] Asynchronous DS3 = Asynchronous mapping of DS3 in
STS1, DS3 channelized to DS1's - asynchronous mapping of
channelized DS3 to OC-3, so that the actual interface is OC-3
but mapped to three DS3 trunk interfaces (DS1 > DS3 > STS-1
> OC-3).
 [15] UNDEFINED = (Default) Not defined.
Notes:
 For the parameter to take effect, a device reset is required.
 The setting of the parameter should be in coordination with the
parameters SDHFbrGrp_SDHSONETMode and ProtocolType.
 The parameter is applicable only when TDMBusType =
acFRAMERS (2) and PSTNTransmissionType = Optical SONET
