Avaya G860 Media Gateway Boards

The TPM board is a high-density, hot-swappable, compactPCI resource board with a
capacity of 672 DS0 channels, supporting all necessary functions for voice, data and
fax streaming over IP networks. The TPM board provides STM-1/OC-3 (future), PSTN,
ATM and T3 interfaces via its Rear Transition Module (RTM).
The TPM board and RTMs are shown below. The TPM/RTM panel contains Tx and
Rx transceivers for:
1+1 (total 2) PSTN STM-1/OC-3 interfaces (future)
3 T3 (DS-3) PSTN interfaces (6 connectors – 3 RX and 3 TX)
T3 PSTN interface port is an SMB connector with Tx and Rx transceivers.
The TPM/RTM is designed for protection capabilities and provides a unique
Redundant protection functionality. The TPM/RTM/HA/Redundant itself does not
provide any PSTN or ATM ports. The same redundant RTM should be used for both
STM-1 (future) and T3 versions.
Slots 7 to 10 are used for up to 4 TPM boards (including the redundant TPM board)
according to the customer's requirements. The corresponding RTMs are located in the
rear cage of the Avaya G860 Media Gateway Media Gateway in the corresponding
slot.
The appropriate rear RTMs are located in the rear cage of the Avaya G860 Media
Gateway Media Gateway in the corresponding slot. The figures below display the
panels of the TPM board and TPM/RTM.
For redundant N:1 protection, the TPM/RTM/HA/Redundant Standby board is
provided. It contains no port connections and occupies slot 10.
