When the product of peer vender or huawei interconnect,if it has failure, we need collect enough information to remove the failure and provide analysis to remove failure.
(1) The configuration and state of our E1 port . we need snatch the current configuration、interface state and E1 controller state(display controller e1)
(2) Which vender of equipment and interface card does the peer end has, if it is E1 card or passes the protocol converter(G.703)
(3) If the peer end is the equipment of cisco, we need collect configuration information、interface state and E1 controller state(show controller e1)
(4) If the peer end is the equipment of H3C, we need collect configuration information 、interface state
(5) If the peer end interconnect serial port by protocol converter, we need collect configuration information、corresponding serial port state、the type and configuration information of protocol converter(such as if it creates frame、which channel does it assign to communicate、if it undoes CRC4、line encoding、clock and so on)
In the interconnection, we not only need attend the configuration of our puduct and the state of E1 ,but also need attend the peer end.
