44 WAN PIM Configuration
T1 Interface
The T1 interface is a basic Physical Layer protocol used by the Digital Signal level 1
(DS-1) multiplexing method in North America. A T1 interface operates at a bit-rate
of 1.544 Mbps and can support 24 DS0 channels.
The T1 PIM supports the following standards:
ANSI TI.107, TI.102
GR 499-core, GR 253-core
AT&T Pub 54014
ITU G.751, G.703
To configure the T1 interface, use the WebUI or CLI as follows:
WebUI
Network > Interfaces > List > Edit (interface): Enter or select the applicable
option value, then click OK:
WAN Configure: main link
WAN Encapsulation: cisco-hdlc
Click Apply.
Fixed IP (select)
IP Address/Netmask 172.18.1.1/24
CLI
set interface serial1/0 encap cisco-hdlc
set interface serial1/0 ip 172.18.1.1/24
save
E1 Interface
The E1 interface is a standard wide area network (WAN) digital communications
format designed to operate over copper facilities at a rate of 2.048 Mbps. Widely
used outside North America, E1 is a basic time-division multiplexing scheme used
to carry digital circuits.
The E1 PIM supports the following standards:
ITU-T G.703
ITU-T G.751
ITU-T G.775
