If your Cisco MC3810 has BRI S/T voice ports,
connect them to a Private Integrated Services
Network Exchange (PINX).
TheBRI voice portsare wired as terminalequipment
(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
appropriateBRI S/T voiceporton the BRI
voice module (BVM). Ports are labeled
BRI 1 through BRI 4 on an orange
background.
Step 2 Connect the otherend ofeach 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.
