potsPortTestType
Module: CPIWF-MIB
OID (symbolic): CPIWF-MIB::potsPortTestType
OID (numeric): 1.3.6.1.4.1.353.5.10.1.1.3.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is used to specify the type of test to run for POTS ports. There are no results stored locally for a loopback test. The tests involve looping back the media stream at either the codec (PCM loopback) or the AAL2 layer (CPS loopback). In order to run these tests, the CO-IWF must first set the value of this object appropriate to the test that needs to be run. The CO-IWF should then set the value of ifAdminStatus in the corresponding ifEntry to 'testing'. The CO-IWF should verify that the test is in progress by checking that the value of ifOperStatus in the corresponding ifEntry is equal to 'testing'. Once testing is complete the CO-IWF must set the ifAdminStatus to a value other than 'testing'. Note that the LES device must not allow a CO-IWF to manipulate the ifAdminStatus of physical user ports that do not belong to its managed CP-IWF.
What is potsPortTestType?
This read-write enumerated value specifies which loopback test to run on a POTS port: none(1), codecLoopback(2) looping back at the codec, or aal2Loopback(3) looping back at the AAL2 layer, with the CO-IWF setting this before initiating the test via cpIwfAdminStatus. It gives an admin a way to isolate whether a voice-quality problem lies closer to the codec or the AAL2 transport layer. Running a codecLoopback(2) test and getting clean audio back would point the admin toward an AAL2-layer problem rather than a codec fault, since the codec itself tested fine.
