The loopback is
performed on all E1
tributaries.
No loopback is
performed on all E1
tributaries.

E1 loopback location.
Perform E1 local
directional loopback.
Perform E1 remote
internal loopback.
You can use the 4
th
switch to configure the working mode of the RCMS2902-2E1GE-
BL. When the switch is ON, the RCMS2902-2E1GE-BL is forced to work in slave
mode. When the switch is OFF, the network management card or network
management module inserted into the chassis, such as the RC002, automatically
recognizes a working mode.
For example, if the RCMS2902-2E1GE-BL is inserted into the RC002-16 chassis at
local and is inserted at the RC001-1M single-slot chassis at remote, the RCMS2902-
2E1GE-BL at local works in master mode and the one at remote works in slave mode.
As shown in Table 4-1, you can configure E1 loopback test through the DIP switch on the
RCMS2902-2E1GE-BL.
When you configure E1 loopback test through the DIP switch, the local E1 loopback is a
bidirectional one and the remote E1 loopback is a unidirectional internal one. Figure 4-2 and
Figure 4-3 show the location and direction of the local bidirectional loopback and remote
unidirectional internal loopback.
