Information
The
TAS Apollo 802 ISDN Emulator provides end-to-end ISDN
switching capability along with bit oriented impairments,
such as framing errors and D-echo (E-bit) manipulation.
Apollo 802 effectively tests ISDN TA/TE devices, such as
ISDN telephones and ISDN terminal adapters. By combining
switching capability with impairments, Apollo dramatically
reduces the cost and complexity of ISDN TA/TE test
configurations.
Apollo Features
ISDN Network Simulation - Apollo provides two NT
terminations for ISDN TA/TE access, and supports switching
functionality for end-to-end call placement. Switching
functionality makes it easy to conduct performance testing
of ISDN CPE devices and verify call control software.
Network Impairments - Apollo provides two network
impairments to test conformance to CCITT 1.430 standards.
These impairments are framing errors and E-bit manipulation.
Injecting framing errors corrupts the frame synchronization
required by ISDN CPE devices. E-bit manipulation provides
user-programmability of the D-echo bit channel. These
features allow 1.430 conformance testing to be performed
quickly and easily. Apollo 802 also allows manual control
over the 1.430 Activation/Deactivation sequence.
Built-In NT Status Monitor - Apollo displays the network
states for each NT termination. The displays indicate Layer
1 network states (G states) and indicate when Layer 2 (LAPD)
is established.
Built-In Call Progress Monitor - The built-in call progress
monitor displays network side Q.931 call states for easy
verification of terminal software operation.
B and D Rear Panel I/O - Rear panel access allows B channel
monitor/insertion capability and D channel monitor
capability. Independent digital ports exist for the B and D
channels, as well as an analog port for B channel information.
S/T Line Monitor and S/T Trigger - The S/T line monitor
supports oscilloscope connection. This port allows
monitoring of the 192 kb/s bit stream on the ISDN S/T
interface. The S/T trigger is programmable, which enables
you to zoom in on any section of the bit stream.
Remote Control - RS-232 and IEEE-488 (GPIB) control are
standard with Apollo. Remote control commands are simple and
easy to use, and are the same regardless of the remote
control method. This makes it easy to include Apollo in
automatic test systems.
RS-232/GPIB Command Translator - Apollo can act as the GPIB
controller in an automatic test system. The controller
issues commands to Apollo via RS-232, and Apollo controls
the rest of the test station via GPIB. This allows any
standard PC to act as a GPIB controller without additional
GPIB control hardware or software.
Software Cartridge * The feature set lor Apollo resides on a
plug-in software cartridge. You can easily add new test
capabilities and different switches as they become available.
