Description

The Digital Central Office Switch Simulator (DCOSS) converts a Pentium PC (portable, tower, rack-mount) into a digital central office switch simulator, PBX and switch, complete with T1, E1, and POTS Interfaces.

A user-friendly graphical interface (GUI), through which complex switching, signaling, and digital transmission functions are easily controlled, provides the ease of operation as well as the flexibility required from telephony test equipment. DCOSS is ideal for simulating and testing advanced telecom networks and products, including switches, gateways, and transmission systems. The DCOSS can also be used for verifying T1/E1 signaling protocols of new systems. These protocols include a variety of T1/E1 CAS, PRI ISDN, SS7 and SS5.

• Manual or Automatic ANI (Caller ID) Generation



• Remote Access Capability (Client/Server) using GUI or Command Prompt. Access to OCX/DLL to develop user-defined client.



• Automatic Bulk Call Generation/Reception for load testing digital/analog trunks



• Bulk Call Scripting with simple point-and-click script setup. Allows for conditional commands as well as script looping.

DCOSS provides the solution required for testing switches, gateways, and networks using a variety of signaling protocols. As depicted below, DCOSS can simulate both ends (or one end) of a complex switching network with a variety of traffic generators (both internal and external). DCOSS can also be controlled remotely using the optional Client/Server application. The Remote Capability allows full control of many DCOSS's from a single client as well as many clients accessing a single DCOSS.

Simulating traffic and analyzing traffic are integral parts of a central office simulator test tool. DCOSS provides the functionality of bulk calling and utilizes a user-friendly GUI for configuring simplistic as well as complex scenarios on a per-timeslot basis. When more complex configurations are desired, including conditional statements and Do Loops, DCOSS provides Bulk Call Scripting, which utilizes a point-and-click interface for creating and editing bulk call scripts.

Using the DCOSS graphical interface, complex switching solutions can easily be configured while providing total voice/data throughput. As depicted below, protocol conversion is accomplished during call switching.
