Model 458-3SL

Chassis

Product Brief

- The Model 458-3SL is used with our advanced 458 Line Modules that simulate several cable types and offer the bandwidth requirements for today’s Xdsl technologies such as varieties of ADSL, G.Lite, HDSL, HDSL2, G.SHDSL(Annex 1), SDSL, VDSL and VDSL2.

- Accept One, Two or Three Plug-In Line Modules.

- The built-in Control Module interfaces with a PC via Ethernet, IEEE-488 or RS232 to control loop-length settings, or it can be used as a stand-along unit.

- Line length is displayed on the front of the unit and can be set via a keypad.

- The same software is used for the 458-2SL and 458-CM(for the 16-Slot chassis)

Model 458-2SL

Chassis

Product Brief

This compact unit is extremely easy to use and a perfect fit when only one or two-channel operation is required. Telebyte Model 458-2SL Chassis is ideal when testing DSL modems and other bandwidth-compliant telecom devices in a high-volume production line environment. The built-in Control Module interfaces with a PC or terminal via IEEE-488 or RS-232 to control loop-length settings or it can be used as a stand-alone unit. User-command language may be used for control of line modules. In addition, line length is displayed on the front of the unit and can be set via a rotary encoder. Our software is field-upgradeable through the RS-232 port. The same software is used for the 458-2SL and 458 chassis.

The Model 458-2SL is used with our advanced 458 Line Module series to simulate several cable types and offers the bandwidth requirements for today’s xDSL technologies such as ADSL, ADSL2, ADSL2+, G.Lite, HDSL, HDSL2, G.SHDSL (Annex 1), SDSL, VDSL and VDSL2.

Model 458

Chassis

Product Brief

The 458 Series 16-slot Chassis, which consists of the 458-CC chassis and one of three control modules, provides a wide variety of configurations through use of up to 16 plug-in Line Modules. It is ideally suited for testing DSL modems and other bandwidth-compliant telecom devices in a high-volume production-line environment. The unit interfaces with a controlling PC or terminal via IEEE-488 or RS-232 to control loop-length settings. A user-friendly interface or user-command language may be used for control of the line modules.

The Model 458-CC Chassis is used with our advanced 458 Line Module series to simulate several cable types and offers the bandwidth requirements for today’s xDSL technologies such as varieties of ADSL, G.Lite, HDSL, HDSL2, G.SHDSL (Annex 1), SDSL and VDSL2.

Model 459A

Chassis

Product Brief

The sleek design, reliability and low cost of the Telebyte Model 459-A makes it the right choice for the production test environment. In addition, loop lengths are programmable from 4 kft to 22 kft, in 2-kft increments (plus 26 kft. The Model 459-A is ideally suited to test DMT DLSAM channels and modems. The Model 459-A simulates 26 AWG PIC and offers the bandwidth requirements for xDSL technologies such as ADSL, G.Lite, HDSL, HDSL2, G.SHDSL (Annex 1) and SDSL.

Product Specifications

Simulation	Accurately represents attenuation and impedance characteristics of 26 AWG PIC as specified in ANSI T1.413.
Accuracy	+/- 6.5%, +/- 1 dB to ANSI Standard    |    +/- 1 dB channel to channel uniformity
Bandwidth	DC to 1.1 MHz bandwidth
Maximum voltage tip – ring	50 volts peak
Maximum continuous current	25 mA
Size	3.47 in H x 19 in W x 14 in D (88.1 mm H x 482.6 mm W x 355.6 mm D)
Connectors	One RJ-45 for RS-232 control Two RJ-21s for 24-channel loop in and loop out One power jack (5.5 mm OD, 2.5 mm ID)  Connections to the units under test are by means of two industry standard 50-pin (RJ-21) Telco/Champ type connectors. The use of twisted-pair cable is highly recommended for connection to the units under test.
