Function
The RC3000E-UP-8E1 is an 8-way uplink interface card on the RC3000E. It can transmit 8 ways of E1
services.
Support channel protection.
Support configuring the 8-way E1 interface on the card to balanced or unbalanced mode through a DIP
switch.
The E1 interface adopts the DB37F male interface connector.
All uplink cards of the RC3000E support E1 protection switching. The number of
supported protection pairs is different according to different uplink cards.
At present, the uplink card supports up to 4 E1 protection pairs:
E1-1 and E1-2
E1-3 and E1-4
E1-5 and E1-6
E1-7 and E1-8
Switching conditions:
In E1 transparent mode, LOS or AIS is generated.
In E1 framed mode, LOS, LOF, or AIS is generated.
Switching time:
When LOS, LOF, or AIS is generated, switching time <1ms.
When CRC4 is enabled, you can configure E-3 as a switching condition. In this
case, the switching time <2s.
Switching modes:
Automatical switch (AS): it can be further divided into revertive and non-revertive
modes.
Manual Switch (MS): traffic will be manually switched to the protection line when
the working line fails. MS will not be executed when both the working line and
protection line work normally or fail.
Forced Switch (FS): traffic will be forcibly switched to the specified line on matter
the switched line works normally or not.
Lockout protection: traffic is transmitted on the working line until the lockout
protection is cleared.
In addition, you can configure the unidirectional revertive mode and unidirectional
non-revertive mode. By default, it is in unidirectional non-revertive mode.
Unidirectional switching: switching is executed without notifying the peer device.
Revertive mode: the switched line can revert to the active mode automatically
when it recovers. You can configure the reversion time through the software.
