Tributary Fiberhome Fonsweaver 780B Low Power Consumption 1:5 TPS Protection
Overview
The E155-8 card is used as a tributary card in the system, and can provide eight 155M electrical signal interfaces by working together with the service terminal board HPIF Card and the protection terminal board HPIFP Card. It supports one 1:5 TPS protection group or two 1:2 TPS protection groups.
-
Implements the 155Mbit/s mapping / demapping.
-
Supports the SOH (section overhead) processing and supports all the defined SOH bytes (such as A1, A2, J0, B1, B2, S1, M1, H1, H2, H3, E1, E2, F1, D1 to D12, K1 and K2).
-
Supports monitoring of the higher order path overheads (such as J1, B3, C2 and G1).
-
Supports the equipment loopback and line loopback tests.
-
Supports one 1:5 protection group or two 1:2 protection groups.
-
Supports the seamless switch between the active and standby clock and crossconnect cards.
