November 2001 

 

7. ETU/TTU-G64 

   

G.703/64K Module

: 

Provides one fully ITU-T compliant G.703 
Codirectional (line code) 64Kbps 
interface on a female "D" type 15 pin 
connector. Operates at 64Kbps only. 
 
 

8. ETU/TTU-NRZ 

   

NRZ Module

: 

Provides one NRZ interface on four(4) 
female BNC type connectors. Operates at 
any n56/n64 fractional or unframed E1 
speed. 
 

9. ETU/TTU-ET10R 

   

Ethernet Router Module

: 

Provides an Ethernet (IEEE802.3 or 
IEEE802.3u) Router function over the 
WAN when matched to another ET10R 
module, IPR Pro standalone, or a 
compatible router under PPP or Frame 
Relay protocol. The interface connection 
is a straight (MDI) 10/100BASE-TX 
Ethernet on a shielded RJ-45 connector. 
Configuration is via RS-232 terminal or 
via proprietary Windows® based GUI 
software. Operates at any n56/n64 fractional or unframed E1 speed.
