14.0 FRACTIONAL-T1 INTERFACE 

CARD 03-3846A01

FRACTIONAL-E1 INTERFACE 
CARD 03-3846A02

14.1 Introduction

The Fractional-T1 (FT1) and Fractional-E1 (FE1) Interface cards are 
optional assemblies which provide additional connectivity within a 
LEDR network for all subrate (S) models. The installation of the 
FT1/FE1 Interface card inside the radio allows the standard EIA-530 
customer data interface to be bypassed and the radio data lines to be con-
nected directly to a G.703 T1 or E1 interface.

With the optional FT1/FE1 Interface, users are able to place a LEDR 
link from a network service access point to a remote site, where an 
installation supports multiple communications devices. Direct interface 
to customer equipment, such as channel banks, is possible without the 
use of expensive protocol converters.

14.2 Fractional-T1/E1 Performance

The FT1 and FE1 Interface allows the LEDR radio to be connected 
directly with a G.703 T1 or E1 interface. The line rate of the interface 
operates at the T1 rate of 1.544 Mbps, or E1 rate of 2.048 Mbps. Twelve 
user selectable DS0 timeslots are transmitted over the air in either case. 
The FT1 interface is G.703 at 100 

Ω

 line impedance. The FE1 interface 

is G.703 at 120 

Ω

 line impedance. Physical connection is via an RJ-45 

jack on the rear panel.

SNMPc™ Network 
Management Manager 

SNMP Management Software to access 
the LEDR embedded SNMP agent, 
allowing management of the LEDR radio 
network and any interconnected SNMP 
enabled peripherals. 

For Windows 98 or NT O/S.
