Product features

· Provides adaptation between two E1/T1 ports and one Ethernet port.

· Provides four 100Base-TX Ethernet electrical ports and one 100Base-FX Ethernet optical port. Two 100Base-TX Ethernet electrical ports are used as upstream ports, two Ethernet electrical ports are used as local data ports, one local data port is used as a monitoring interface, and one Ethernet optical port is used as either an upstream port or a local data port.

· It supports circuit simulation of E1 services over Ethernet links, supports SAToP protocol, and supports IP/UDP packet encapsulation. Support E1 packet QoS guarantee.

· E1 port clock mode Supports local ringing clock, adaptive timing, and E1 port loopback clock.

· Two upper Ethernet electrical interfaces support 1+1 non-destructive protection.

· The Built-in Layer 2 switching function of Ethernet supports 802.1Q VLAN and QinQ switching. Supports port-based, 8021.1p and TOS QoS; Supports port rate limiting, traffic control, automatic MAC address learning, and MAC address aging time.

· Supports 120-Ohm _E1/100-Ohm _T1 ports in RJ-48C form, and can be converted into 75-Ohm off-balance ports through the dial setting on the baseboard and special cables to realize impedance matching.

· High transmission efficiency, low transmission delay;

· Stable frequency reduction, small jitter and drift;

· Strong packet loss resistance, no frequency jump, super frame synchronization protection;

· Support cache absorption function to resist packet delay change;

· Support web Server network management, remote monitoring, easy operation and maintenance;

· Supports SNTP network synchronization.

· E1 bit error tests are supported
