This manual explains how to configure E‑carrier (E1, E3) and T‑carrier (T1, T3) interfaces on routers running the VRP (Versatile Routing Platform). It describes the two working modes—clear channel and channelized—for each interface type and provides example configuration files for both E‑carrier and T‑carrier setups.
The document also details the data rates and timeslot structures of each carrier type, and includes step‑by‑step commands for creating channel sets, assigning timeslots, and activating the interfaces on routers such as RouterA and RouterB. This manual is written in Chinese.
