Module: Nortel-MsCarrier-MscPassport-VnetEtsiQsigMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-VnetEtsiQsigMIB::mscSigChanEQsigE1ChannelNumbers

OID (numeric): 1.3.6.1.4.1.562.36.2.1.115.2.18.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute is applicable to E1 interfaces only. It specifies the mapping scheme between channel numbers (identified in Layer 3 messages) and timeslot numbers on the E1 link. When the attribute value is skip16, channel numbers map directly to actual E1 timeslots; therefore only channel numbers 1 - 15 and 17 - 31 are expected. When the value is contiguous, channel numbers from 1 - 30 are expected, and the following mapping is used: channels 1 - 15 are mapped to timeslots 1 - 15, and channels 16 - 30 are mapped to timeslots 17 - 31. On T1 interfaces, channel numbers are always expected in the range 1 - 23.

What is mscSigChanEQsigE1ChannelNumbers?

This OID sets the E1 channel-to-timeslot mapping scheme for this EtsiQsig interface: skip16(1) - the default - maps channel numbers directly to timeslots (skipping timeslot 16), while contiguous(2) maps channels 1-30 sequentially onto timeslots 1-15 and 17-31. Admins set this to match how the connected PBX numbers its E1 channels; it doesn't apply to T1 interfaces, which always use channels 1-23.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.115.2.18.1.2
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-VnetEtsiQsigMIB::mscSigChanEQsigE1ChannelNumbers

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.115.2.18.1.2.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-VnetEtsiQsigMIB::mscSigChanEQsigE1ChannelNumbers.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.115.2.18.1.2.1 i <value>
