Overview of Cisco Network Modules 1-7
Cisco 2600 Series Routers
•
Slot 1, serial interface 0, referred to as serial 1/0
•
Slot 1, BRI interface 0, referred to as BRI 1/0
Note The 2E 2-slot module described in this example provides both an attachment unit
interface (AUI) and 10BaseT port. Only one of these ports can be used at a time. The
module automatically detects which port, AUI or 10BaseT, is in use.
Voice Interface Numbering in Cisco 3600 Series Routers
Voice interfaces are numbered differently from WAN interfaces described in the previous
section, “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 chassis slot 0)
•
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 chassis slot 0)
