•
SDHFbrGrp_SDHSONETMode - set to 'STM1' (1)
•
SDHFbrGrp_Mapping_Type - set to 'Asynchronous TU12 and E1' (1)

OC-3 interface: provides short range SONET OC-3 interface compliant to GR-253-
CORE and ANSI T1.105. The interface operates at 155.52 Mbps over a single-mode
fiber span. The following mapping types in OC-3 are supported:
•
Asynchronous VT1.5 (DS1 > VT1.5 > STS-1 > OC3) - mapping of T1s into
VT1.5s and multiplexing of 84 VT1.5 into an OC-3 frame
•
Byte-synchronous VT1.5 (DS1 > VT1.5 > STS-1 > OC3)
•
Asynchronous mapping of DS3 in STS1, DS3 channelized to DS1s (DS1 > DS3 >
STS-1 > OC3)
Relevant parameters:
•
PSTNTransmissionType - set to 'Optical SONET or SDH' (1).
•
SDHFbrGrp_SDHSONETMode - set to "OC3" (2)
•
SDHFbrGrp_Mapping_Type set to one of the following:

The blade supports Trunk Numbering:

STM-1: trunk numbers are in the range of 0 to 62 (E1s)

OC-3: trunk numbers are in the range of 0 to 83 (T1s)
Trunks are numbered according to ETSI EN 300 417-1-1, Annex D recommendation.
