PCM30) or 11 channel (1E1 as PCM31), to user sub-card, and occupy 21-30/31 channel of the first
E1. RC3000 will automatically assign 14 channels to user sub-card, and occupy 17-30 channel of the
first E1
RC3000 does not cross connect idle channels except RC3000-2E1 (ADM). RC3000-2E1 (ADM)
cross connect the same idle channels of E1 1 and E1 2 to realize the transfer between E1 1 andE1 2.
RC will first use valid cross connect configuration information saved in memory, and erase invalid
configuration information automatically. Rules for cross connection are as follows:
a.
information is invalid.
b.
c.
saved in memory.
d.
looking for other idle channels for distribution.

5.1.6 System and crossover setting

RC3000 has rich configuration information for any E1 interface and signaling interface to realize all
kinds of cross connect. Please refer to appendix A. how to use Hyper Terminal to configure RC3000.

5.1.7 Device alarms

There are two kinds of alarms: 1. device alarms; 2. system alarms. Device alarms indicate E1 line
and optical interface alarms, and optical interface alarms include:
RC3000-OPT-2E1 includes LOS alarm at E1 interface as below:
E1 interface alarms:
All configurations will be refreshed if the line-board is changed and all saved cross connect
When sub-card is pulled out, the corresponding cross connect information will be erased.
If the same type sub-card is put into the same slot, system will restore cross connect information
If new type sub-card is put in, system will first distribute the idle channels of E1 1 and then
