accDs1ExtSignalGroup
Module: ACC-DS1
OID (symbolic): ACC-DS1::accDs1ExtSignalGroup
OID (numeric): 1.3.6.1.4.1.5.1.1.42.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The index of the Signal group assigned to this interface. The value of the trunk group index is limited to the maximum number of PRI interfaces that can be installed on a given platform (3 for Amazon, 28 for Tigris). A trunk group value of 0 indicates that the interface does not belong to a PRI trunk group. Replaces accDs1ExtNfasGroup which has been deprecated.
What is accDs1ExtSignalGroup?
This OID assigns a PRI trunk group index (0–127) to this DS1 interface, grouping multiple DS1 lines for unified call signaling and load balancing, with 0 indicating no group assignment. Network engineers configure this to combine multiple T1 or E1 lines into logical trunks for telecom services like PRI (Primary Rate Interface), with limits depending on hardware (3 on Amazon platform, 28 on Tigris). For example, setting accDs1ExtSignalGroup to 1 places this interface in trunk group 1, so its 23 B-channels (or 30 for E1) are pooled with other group-1 interfaces for call routing.
