Introduction
The Model 458-LM-E1-36-04 Multi-Standard Local Loop Simulator is the ideal solution for
ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing. This single-pair loop
simulator can simulate PE04 for ADSL, ADSL2, ADSL2+ and VDSL2 (including Profile 35b).
This versatile local loop simulator is plugged into our Model 458-3SLB (3-Slot) or 458-CC-16
(16-Slot) chassis where settings are controlled by a convenient keypad located on the front,
RS-232, Ethernet or IEEE-488(GPIB). In addition, the user-friendly 458 Universal GUI may be
used for remote control. The modular design of Telebyte’s products allows the 458-LM-E1-36-
04 to be combined with other line modules for a wide variety of test configurations.
Main Features:
•Simulates PE04 as specified in ETSI TS 101 388
•One Channel
•Bandwidth DC to 36 MHz
•Line lengths from 0 –9,000 m in 10-m steps
•Solution for ADSL, ADSL2, ADSL2+, & VDSL2 (including Profile 35b)
•Ideal for testing TR-114 Issue 3
•Plugs into our Model 458-CC (16-slot) or 458-3SLB (3-Slot) chassis
•Loop Lengths controlled manually via front panel of chassis, or remotely via RS-232,
Ethernet, IEEE-488 (GPIB), or 458 Universal GUI

Remote Commands
Please refer to the manuals for the 458-3SLB or 458-CC-16/458-CM for remote commands
common to many line modules, including the 458-LM-E1-36-04. This manual contains
commands unique to this module.
RS-232 (Serial Port) Remote Commands
Set Length Command Values: SL:M:LE,C
Where,
SL = set length
M = module (slot) number 01 –16 (458-CM) or 01-03 (458-3SLB)
LE = length from 0 –9,000 m in steps of 10 m
C = connect mode
N = connect both CO and CPE ends
P = connect CPE only CO open
O = connect CO only CPE open
Z = open both CO and CPE ends
Example:
SL:02:9000,N = Set length of module in slot 02 to 9000 meters with both CO and CPE
connected.
