Newsletter: GL Enhances Digital Central Office Switch Simulatior (DCOSS)
Welcome to the June 2010 issue of GL Communications' Newsletter providing information on latest enhancements
introduced to our versatile Digital Central Office Switch Simulator (DCOSS) product - a
powerful simulator for telecommunications networks. A snapshot of the capabilities is shown below.
The DCOSS is a high density switch and a comprehensive traffic generator which supports
large volumes of any traffic including voice, fax, modem, and tones. Unique applications of the
DCOSS include Lawful Interception, Automated Attendant, IVR Testing, Gateway/ATA modem
and fax testing, and SS7 Network simulation. For instance, being a self-contained system with capabilities to easily
communicate with external networks, the DCOSS can support an entire SS7 network including
LNP, GTT, internal traffic and external phones. Routing and hunt groups are fully supported and configurable.
DCOSS is ideal for simulating and testing advanced telecom networks/products including
switches, gateways, and transmission systems. DCOSS is a central office switch with both T1 and E1 trunks along with
analog and BRI ISDN phone interfaces. DCOSS supports a multitude of protocols including SS7 (SSP/STP/SCP), PRI ISDN
(all variants ) and CAS (MFC-R2, E1 CAS, and T1 CAS). The DCOSS CAS State Machine provides the versatility of a
user-defined script for simulating custom CAS protocols.
DCOSS provides carriers and other operators with the ability to test virtually all elements
of their networks. In addition, it provides a user-friendly GUI, remote client access (GUI, CLI, SDK), and scripting with which
users can capture the performance of networks in a wide variety of scenarios.
New Features & Enhancements Introduced in Latest DCOSS version:
- New DCOSS T1/E1 Hardware
The DCOSS has been enhanced to support the latest T1/E1 hardware. The latest DCOSS
provides backwards compatibility for the previous versions of T1/E1 hardware as well. And it supports only Windows XP
- CLI/SDK Support
Several new enhancements have been added to the DCOSS Remote for additional
flexibility when using the remote Client. This includes send/record individual traffic (voice files, digits, tones, fax), access
to the SS7 Link Status and increased status of the DCOSS Bulk Calling.
- SS7 Enhanced Support
From the DCOSS GUI or the Remote Client, the individual SS7 Signaling Links can be
enabled and disabled. This provides added flexibility when testing the SS7 network.
- Bulk Call Scripting
In order to provide greater flexibility and communication within a running Bulk Call script, the
DCOSS can send user-defined events between two scripts. The user-defined events allow for
proper synchronization and positive feedback between the two sides of a call.
- CAS State Machine
The DCOSS supports auto start of the CAS State Machine script after loading the T1/E1
- Fax support
The latest T1/E1 boards provide full fax capability without additional hardware. In other words, there is now a
software option to provide minimum fax or full fax on all boards within the DCOSS (not
board specific) when using the latest T1/E1 hardware.
