E1 service

Hello, friend!

The following terminals support the TDM (E1) service:

1. OT925G: provides four E1 ports for connecting devices such as the PBX, wireless base station, and node server.

2. OT928G: provides eight E1/T1 ports for connecting devices such as the PBX, wireless base station, and node server.

Both the GPON OLT and the EPON OLT support E1 services. The TOPA board provides two 8-channel E1 ports to implement upstream conversion to 2 Mbit/s.Works with the preceding terminals that support E1 services to implement the TDM leased line function.

TOPA can implement its functions only when it is configured with the corresponding daughter board. Currently, the following daughter boards are supported:

NH1A: provides 16 E1 ports, supports the upstream transmission of TDM signals, and implements the native TDM function.

EH1A: provides 16 E1 ports, supports TDM signal upstream transmission, and implements the CESoP function.

Thanks!
