Voice Interface Numbering in Cisco 2600 Series Routers
Voice interfaces are numbered differently from WAN interfaces described in the previous
section, "Slot and Unit Numbering." Voice interfaces are numbered as follows:
interface type chassis slot/voice module slot/voice interface
If you have a four-channel voice network module installed in slot 1 of your router, the voice
interfaces will be:
•
Slot 1, voice network module slot 0, voice interface 0, referred to as voice 1/0/0 (closest
to the chassis WAN interface card slots)
•
Slot 1, voice network module slot 0, voice interface 1, referred to as voice 1/0/1
•
Slot 1, voice network module slot 1, voice interface 0, referred to as voice 1/1/0
•
Slot 1, voice network module slot 1, voice interface 1, referred to as voice 1/1/1 (farthest
from the chassis WAN interface card slots)
