Default: E1
1 ~ 5
E1 data size encapsulated in E1/T1, N=1~5 optional,
corresponding to 256×N byte(E1).The bigger the packet is the
more data each packet encapsulated, the lower overhead it
has. Bandwidth efficiency will be raised and delay will be
increased.
Default :2
Yes
(Default) Yes: IP encapsulation, source and destination IP
address should be set. Could pass router, Bandwidth efficiency
will be reduced.
No: do not use IP encapsulation, can not pass router, high
bandwidth efficiency.
No
(Default) Yes: IP encapsulation, source and destination IP
address should be set. Could pass router, Bandwidth efficiency
will be reduced.
No: do not use IP encapsulation, can not pass router, high
bandwidth efficiency.
16 E1/T1 ports
E1/T1 service No.: Supports max. 20 upper/lowercase letters,
digit and some special character inputs. Does not support
some special characters such as “/” and “\”.
Enables the channel of E1/T1.
Default: Enable
Remote end IP address: 4 E1 line IP addresses can be set
separately.

2~120ms
Jitter absorption buffer: Used to buffer the receiving packets.
Incoming packets are buffered to eliminate jitter.
Range: 2~120ms
Default: 16ms
Each E1/T1 connected equipment IP address, could be set
respectively.
Default:192.168.1.3
Select corresponding relation of local T1/E1 ports to remote
T1/E1 port service.
