GL Communications Inc., a provider of test equipments for TDM, wireless, IP and VoIP networks, announced that it has enhanced its Digital Central Office Switch Simulator hardware and software.According to GL Communications (News – Alert), the Digital Central Office Switch Simulator “DCOSS” is ideal for simulating and testing advanced telecom networks and products, including switches, gateways, and transmission systems. This central office switch with both T1 and E1 trunks along with analog and BRI ISDN phone interfaces can convert a Pentium PC (portable, tower, rack-mount) into a digital central office switch simulator, PBX (News – Alert) and switch.
In a press release, Robert Bichefsky, senior manager at GL, said that the company’s DCOSS is a high density switch and a complete traffic generator that supports large volumes of any traffic including voice, fax, modem, and tones.
Some of the unique applications of the DCOSS include lawful interception, automated attendant, VR testing, gateway/ATA modem and fax testing, and SS7 Network simulation. The DCOSS can support an entire SS7 network including LNP, GTT, internal traffic and external phones, added Bichefsky.
According to Bichefsky the DCOSS offers carriers and other operators with the ability to test virtually all elements of their networks. It can be utilized for verifying T1/E1 signaling protocols of new systems as well. It can support a multitude of protocols such as SS7, all variants of PRI ISDN and CAS. The simulator also provides a user-friendly graphical user interface “GUI,” remote client access, and scripting with which users can capture the performance of networks in a wide variety of scenarios.
Some of the new enhancements to latest DCOSS version include new DCOSS T1/E1 hardware that supports the latest T1/E1 hardware and Windows XP operating system; send or record individual traffic for voice files, digits, tones, and fax; access to the SS7 link status; the individual SS7 Signaling Links can be enabled as well as disabled for added flexibility; bulk call scripting; support for auto start of the CAS State Machine script after loading the T1/E1 trunks; fax support; and more.
Apart from the above discussed enhancements, the latest DCOSS version also includes backwards compatibility for the previous versions of T1/E1 hardware. It can send user-defined events between two scripts to provide greater flexibility and communication within a running Bulk Call script. The user-defined events will facilitate for proper synchronization and positive feedback between the two sides of a call.
The company’s TDM analysis and emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Some of the capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, frame relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and more.
In the recent news, TMCnet had reported that GL communications introduced a broad range of Echo Canceller Compliance Testing Solutions. Apart from this news, GL Communications recently also announced its enhanced T1 E1 Line Management System.
