MG-IP TDM Over IP Gateway Reference Manual

dsx1LineMode Functionality
dsx1LineMode setting is supported in E1 as well as in T1. This is an extension to the standard, which
defines T1 setting only.
PW Name Issues
OlencomPwName is mandatory. It must be a unique name of up to 31 characters. It is the responsibility
of the manager to provide this unique name.
Pseudowire PSN Type
The type access is read-only. PSN types change dynamically according to the TDM circuit attached to
them.

PW Admin Status Behavior and TDMIfIndex Assignment
A pseudowire cannot be enabled (OlencomPwAdminStatus = “up”) when there is no TDM port or
DS0-bundle with timeslots assigned. For this reason, the default status is set to “down”. The following
actions must be taken when creating a pseudowire:
1.
Create a pseudowire in the OlencomPwTable
2.
Set the relevant DS1 or DS0-bundle index to OlencomPwTDMIfIndex
3.
Set admin status to “up”
Usage of OlencomPwOutboundLabel and OlencomPwInboundLabel in OlencomPwTable
The parameters OlencomPwOutboundLabel and OlencomPwInboundLabel are defined in the standard
to be used when the pseudowire is configured for transport using MPLS or L2TP.
Olencom’s implementation uses these parameters to Set and Get the UDP destination and source ports,
respectively, when OlencomPwPsnType is defined as “IP”. This is performed as the draft does not
describe MIB parameters for this purpose. In the future, a draft (then a standard) MIB may be defined
for storage of UDP parameters.
Usage of OlencomPwOutboundLabel and OlencomPwInboundLabel in OlencomPwTable
Currently, payload size needs be set in frames. OlencomPwTDMCfgXPayloadFrames is used to
achieve this. OlencomPwTDMCfgPayloadSize is read-only and changes according to the payload
configured in frames and the bandwidth of the TDM circuit assigned to the pseudowire.
Interaction between OlencomPwTDMTable and OlencomPwTDMCfgTable
The draft calls for OlencomPwTDMCfgTable entries to be created. These entities can then be assigned
to entries contained in the OlencomPwTDMTable. More than one OlencomPwTDMEntry may point to
