1.1
WPIM-RT1 FEATURES
 
The WPIM-RT1 extends the functionality of the Wide Area Network host 
platform to provide a full or fractional T1 interface for the CSX400, 
HSIM-W6, or the HSIM-SSA710. The WPIM-RT1 provides a T1 
interface that includes a built-in Channel Service Unit/Digital Service 
Unit (CSU/DSU) for direct connection to a T1 line. 
 
1.2
WAN PROTOCOLS
 
The WAN protocols that are supported are determined by the host 
platform in which the WPIM-RT1 is installed. Refer to the host platform 
manual to find the protocols supported.
 
1.3
ISDN
 
ISDN provides inexpensive switched digital access to remote sites. The 
ISDN BRI standard provides for two high speed 64 Kbps bearer (B) 
channels used for voice or data connections and one 16 Kbps signaling 
data (D) channel used for call setup, signaling and other information. 
ISDN allows all types of information to be transmitted including voice, 
data, fax and video. Multiple devices can be linked to a single ISDN 
connection, each having their own telephone number. Two or more 
channels can be combined into a single larger transmission pipe offering 
variable transmission speeds.

MIB SUPPORT
 
Refer to the Release Notes included with the host platform for a list of all 
MIBs supported by the WPIM-RT1. For information about how to extract
