RC3000-4E1: single E1 direction.
RC3000-2E1: single E1 direction when it is not in ADM mode; dual-E1 direction when it is in ADM
mode.
5.1.4 Clock switch explanation
By factory default status, clock mode of RC3000 is slave clock (trace the E1 1); the device can
switch clock by automation in clock auto-switch mode according to practice synchronous status so
that all devices can work under a uniform clock. You can also set the work clock manually. Once
powered on, RC3000 will first synchronize with configured clock. If this clock is invalid, in
auto-switch clock mode RC3000 will switch the clock according to work status and in manual clock
mode, it will keep history configuration.
Suggestion: please be attention to clock mode when organizing your network with lots of RC3000s
and make sure of uniform clock.
5.1.5 Automatic crossover setting
By factory default status, RC3000 can cross connect sub-card channels with first user E1. For simple
application RC3000 can work normally without any configuration. Details are as follows: Sub-card
in first slot:
If the number of channels on the user sub-card can not be set for the state, allocate in accordance
with the number of channels inserted the board, for example, eight channels, in 8-line mode these 8
channels will be automatically assigned to 1-8 channel of the first E1. If the user sub-card, in 10-line
mode these 10 channels will be automatically assigned to 1-10 channel of the first E1. IF the number
of channels can be set for the state, in 10-line mode RC3000 will automatically assign 8 channels to
user sub-card, and occupy 1-10 channel of the first E1.
In second slot:
If the number of channels on the user sub-card can not be set for the state, allocate in accordance
with the number of channels inserted the board, for example, 4 channels, in 8-line mode these 4
channels will be automatically assigned to 9-12 channel of the first E1. If the user sub-card, in 8-line
mode these 8 channels will be automatically assigned to 9-16 channel of the first E1. IF the number
of channels can be set for the state, in 10-line mode RC3000 will automatically assign 10 channels to
user sub-card, and occupy 11-20 channel of the first E1.
In third slot:
If the number of channels on the user sub-card can not be set for the state, allocate in accordance
with the number of channels inserted the board, for example, 8channels, in 8-line mode these 8
channels will be automatically assigned to 17-24 channel of the first E1. If the user sub-card, in
10-line mode these 8 channels will be automatically assigned to 21-28 channel of the first E1. IF the
number of channels can be set for the state, in 8-line mode RC3000 will automatically assign 14
timeslot (1E1 as PCM30) or 15 timeslot (1E1 as PCM31) to user sub-card, and occupy 17-30/31
channel of the first E1; in 10-line mode RC3000 will automatically assign 10 channels (1E1 as
