Stop the IP circuit emulation, the system shows 2M Link OUTPUT Error. This is

because when stopping circuit emulation, the 2M input/output is stopped as

well.

Then input 2, input the basic configuration information.

The basic configuration information includes subnet mask, local IP address,

default net gate and IP circuit emulation IP address, E1output clock and time

delay parameter.

As to E1 output clock: in the IPCE-X equipment, E1 output clock is optional.

There are totally four clocks to choose. 0 is network adapting clock. 1 is loop

clock, namely E1 input clock. 2 is internal clock. 3 is output clock. Network

adapting clock is IPCE recovers the E1 clock from according to the received

data. The customers can choose approximate clock according to the concrete

network conditions. What is more, the right clock configuration is the base of

the IPCE working well.

As too time delay coefficient: because IP network is a package switching

network, and E1 is circuit transportation, in order to let them be compatible,

buffer forward is necessary in IPCE. And of course this causes time delay.

Under the condition that network jittering is small, time delay coefficient can be

set smaller, and this can reduce the time delay. But under a bad network
