
Support configuring the number of channels.

Support phase adjustment.

Support loopback configuration and BERT.
The number of occupied channels by the V35 interface can be configured and the
configuration rules are as below.
Rules for automatically allocating channels:

In 8-channel mode, when the V35 card is inserted into slot 1 and channels 1–8 of
the No.1 way E1 are not occupied, the system will automatically allocate 8
channels for the card to occupy channels 1–8 of the No.1 way E1; when the V35
card is inserted into slot 2 and channels 9–16 of the No.1 way E1 are not
occupied, the system will automatically allocate 8 channels for the card to occupy
channels 9–16 of the No.1 way E1; when the V35 card is inserted into slot 3 and
channels 17–30 of the No.1 way E1 are not occupied, the system will
automatically allocate 14 channels for the card to occupy channels 17–30 of the
No.1 way E1 (channels 17–31 when it is the PCM31).

In 10-channel mode, when the V35 card is inserted into slot 1 and channels 1–10
of the No.1 way E1 are not occupied, the system will automatically allocate 10
channels for the card to occupy channels 1–10 of the No.1 way E1; when the V35
card is inserted into slot 2 and channels 11–20 of the No.1 way E1 are not
occupied, the system will automatically allocate 10 channels for the card to
occupy channels 11–20 of the No.1 way E1; when the V35 card is inserted into
slot 3 and channels 21–30 of the No.1 way E1 are not occupied, the system will
automatically allocate 10 channels for the card to occupy channels 21–30 of the
No.1 way E1 (channels 21–31 when it is the PCM31).
Rules for manually allocating channels:

When manually allocating channels, you can configure different limitations
according to different positions of the card. The RC3000E supports 4 ways of E1
and each E1 is a user group. In configuration, 1, 2, 3, and 4 are used to stand for
the No.1, No.2, No.3, and No.4 E1. Moreover, the RC3000E provides 4 groups of
bus and can transmit 4-group user services (2 Mbit/s). In configuration, 5, 6, 7,
and 8 are used to stand for user groups 1, 2, 3, and 4.

User group 1 serves as the main channel and the default channel. Other user
groups are independent channels. Occupied independent channels are different
according to slots. And there are different limitations towards different versions of
the RC3000E products for the use of independent channels. For REV B.00 or
before versions, slot 1 uses user group 2 as the independent channel; slot 2 uses
user group 4 as the independent channel; slot 3 supports no independent channel.
For REV B.00 or later versions, slot 1 uses user group 2 as the independent
channel; slot 2 uses user group 3 as the independent channel; slot 3 uses user
group 4 as the independent channel.

Limitations for main channel configurations: when you use the main channel to
transmit data, there are different limitations for the number configurations of the
channel according to slots. The range for the card in slot 1 is 0–31. 0 refers to
disabling transmission of this card and the channel No. starts from 1. When there
is any other card in later slot occupies the main channel, channel collision alarm
will be reported. The range for the card in slot 2 is 0–23. 0 refers to disabling
transmission of this card and the channel No. starts from 9. When there is any
