Setting Logical Layer Parameters
You must configure logical ports for the E1 ports, as specified in
Table
7-7
. You
must configure the following logical ports:
For RICi-4E1/T1: Logical ports 41 – 44 with PPP over HDLC, which are then
bound to logical port 45 with MLPPP protocol
For RICi-E1/T1: Logical port 46, HDLC protocol
For MiRICi-16E1/T1: Logical port 47, GFP (non-VCAT non-LCAS) protocol with
VCAT header disabled
The logical ports are configured in the Logical Layer menu
(Main Menu>Configuration>Logical Layer).

³ To configure the logical layer for the E1 ports to RICi-4E1/T1:
1. In the Logical Layer menu, configure logical port 41 with PPP over HDLC
protocol, to correspond to physical port 41, as illustrated in
Figure
7-44
.
2. Repeat the same configuration for logical ports 42 to 44, to correspond to
physical ports 42 to 44.
3. In the Logical Layer menu, configure logical port 45 with MLPPP protocol,
binding it to logical ports 41 to 44, as illustrated in
Figure
7-45
.
