TPM (Tributary Protection Module)
The TPMs provide protection to PIMs and electrical SIMs. Client traffic is
connected directly to the TPM, and the TPM is connected by traffic cables to the
XDM-100 main and protection modules. Power and control buses are connected to
the TPM via the TPU backplane.
The TPMs include switching relays that are activated by the active MXC (via the
TCF module) upon detection of a faulty PIM or SIM. When activated, these relays
route the traffic from the faulty to the protection I/O module.
TPMs support 1:1 and 1:3 protection schemes for PIMs and electrical SIMs. A TPM
for 1:1 protection connects to one main and one protection I/O module and occupies
one TPU slot. A TPM for 1:3 protection scheme connects to one protection and three
main modules and occupies two TPU slots.
1:1 and 1:2 protection schemes can also be implemented using 1:3 TPM modules
connected to one protection and one or two main I/O modules.
Four slots are allocated in the TPU shelf to accommodate the various types of TPMs.
TPMxx_1 modules for 1:1 protection schemes can be installed in any of the TPM1
to TPM4 slots without any limitations. Two TPMxx_3 modules (for 1:3 protection)
can be installed in the TPU, or a mixed configuration of one TPMxx_3 and two
TPMxx_1 can also be accepted.
7-1 lists the TPM modules data configuration.
