tdmaCsV42BisP0CompressionDirection

Module: Nortel-Magellan-Passport-TdmaIwfMIB

OID (symbolic): Nortel-Magellan-Passport-TdmaIwfMIB::tdmaCsV42BisP0CompressionDirection

OID (numeric): 1.3.6.1.4.1.562.2.4.1.135.8.10.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute specifies the V.42bis data compression direction to be supported. The value for compression direction is negotiated at link setup by the data link protocol by way of the Exchange Identification (XID) negotiation of parameter P0 (compression direction). During XID negotiation of parameter P0, both sides (IWF and mobile or IWF and PSTN) agree on the compression direction. This attribute has one of the following values: noCompression: No compression is present. compInitrResp: The data sent by the IWF to the other entity is compressed. compRespInitr: The data received by the IWF from the other entity is compressed. compBoth: The data sent and received by the IWF is compressed. Changes to this attribute do not affect existing calls.

What is tdmaCsV42BisP0CompressionDirection?

Selects the V.42bis compression direction negotiated at link setup (XID parameter P0) between the IWF and the far end: noCompression, compInitrResp (IWF-to-peer compressed), compRespInitr (peer-to-IWF compressed), or compBoth. Changes here don't affect calls already in progress.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.135.8.10.1.1
