Connecting BRI S/T Voice Ports
If your Cisco MC3810 has BRI S/T voice ports,
connect them to a Private Integrated Services
Network Exchange (PINX).
The BRI voice ports are wired as terminal equipment
(TE).
• If the PINX ports are wired as network
termination (NT), use 8-conductor
straight-through cables (not included).
• If the PINX ports are wired as TE, use
8-conductor rollover cables (not included).
Note: The BRI voice ports are physically wired as
TE. However, they can be software-configured to
function as either TE or NT.

Step 1
Connect one end of each cable to the
appropriate BRI S/T voice port on the BRI
voice module (BVM). Ports are labeled
BRI 1 through BRI 4 on an orange
background.
Step 2
Connect the other end of each cable to the
appropriate port on the PINX.
Note: BRI ports on the Cisco MC3810 do not
require external power from the PINX when in TE
mode and do not supply power to external devices
when in NT mode.
