4. PN control gateway or carrier in the A position that contains a TN2312AP/BP IPSI circuit pack for IP connection to the server.
5. Duplicated expansion control gateway or carrier in the B position that contains a TN2312AP/BP IPSI circuit pack for IP
connection to the control network
6. IPSI-to-server control network connection by means of an Ethernet switch.
7. LAN connections of a TN2302AP IP Media Interface or a TN2602AP IP Media Resource 320 for voice processing, and
optional TN799DP CLAN for control of IP endpoints.
NOTE: The number of TN2302AP, TN2602AP, and TN799DP circuit packs varies, depending on the number of IP
endpoints, PNs, and adjunct systems. These circuit packs are optional for PNs in a direct-connect network and can
be inserted into a port carrier, as shown in the figure, or in the PN control carrier or the duplicated control carrier.
However, the CLAN circuit pack is required for downloads of firmware updates.
8. Customer LAN.
9. LAN connections of the media servers for remote administration.
10. Duplicated server links, including the link for translations transfer and the link for control data sharing.
11. Remote PN with nonduplicated control (G650 Media Gateway stack, MCC1 Media Gateway, SCC1 Media Gateway stack),
that consists of at least two media gateways or carriers.The figure show the G650 stack.
Replacing the I/O cables
Replacing I/O cables
On older MCC1, SCC1, and G600 media gateways or cabinets, you must replace the existing I/
O cables (WP-90753, LI) with twisted pair I/O cables. These I/O cables connect the backplane
to the rear connector panel.
The existing I/O cables have straight, not twisted, wires. These cables can be mostly white with
two red or multicolored. If the cables have multicolored, tightly twisted wires, no replacement is
necessary.
To order the DEFINITY kit with twisted pair I/O cables, use comcode 700234032.
!
CAUTION:
Turn off power to the carrier or the media gateway before you replace the cables.
CAUTION:
!
CAUTION:
When you add or replace any hardware and associated cables and adapters,
CAUTION:
ground yourself against electrostatic discharge (ESD). Always wear a grounded
wrist strap.
NOTE: For the G650 Media Gateway, the BP version of the TN2312 is required in order to provide
environmental maintenance.
