dclAlternateIdlePattern

Module: Nortel-Magellan-Passport-DcmeMIB

OID (symbolic): Nortel-Magellan-Passport-DcmeMIB::dclAlternateIdlePattern

OID (numeric): 1.3.6.1.4.1.562.2.4.1.130.10.1.6

Node type: OBJECT-TYPE

Type: Hex

Access: read-write

Description: This attribute specifies an alternateIdlePattern in the channel received from the E1 interface, after the end of a 64kbit/s call. The value of this attribute should be different than the value of the idlePattern attribute only if the ISC is programmed for Even/Odd Bit Inversion (EBI/OBI). This is only the case when the ISC is performing A to Mu or Mu to A Law conversion. When the end of the alternateIdlePattern is detected it indicates the start of a new speech call.

What is dclAlternateIdlePattern?

Specifies an alternate idle bit pattern (0-255) used after the end of a 64 kbit/s call; it should only differ from dclIdlePattern when the ISC performs Even/Odd Bit Inversion (A-law/mu-law conversion). Admins set this to match the ISC's bit-inversion behavior so call-boundary detection remains accurate on 64 kbit/s calls.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.130.10.1.6
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-DcmeMIB::dclAlternateIdlePattern

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.130.10.1.6.1
snmpget -v2c -c public <target> Nortel-Magellan-Passport-DcmeMIB::dclAlternateIdlePattern.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.130.10.1.6.1 s <value>
