Each TPM is dedicated for protection of a specific traffic rate and protection
scheme. The TPM name designates the protected traffic rate and the protection
scheme, as follows:
|
The first digit after the name designates the traffic rate.
| The last digit after the underscore designates the protection scheme.
For example, the TPM2_3 is a module for 2 Mbps traffic, and supports a
protection scheme of 1:3.
Similarly TPMH_1 is a module for High rate traffic (including 34/45 Mbps and
155 Mbps), and a protection scheme of 1:1.
The following table summarizes the available TPMs, the type of I/O modules
they protect, the traffic rate, and the protection scheme.

In the specific XDM-300 protection schemes, the location of the protection
module (P) and the protected module (M) is allocated by the system's
management software. Therefore the I/O modules must be installed in the
allocated slots, and connected to the corresponding TPMs.
The following sections provide schematic diagrams and tables for the
connections of the XDM-300 shelf in the various protection schemes.
