Press Release: GL Communications Releases Digital Central Office Switch Simulator (DCOSS) Ver 5.10

Gaithersburg, Maryland, USA - February 2, 2005 - GL Communications Inc., today announced the release of their enhanced analysis and simulation equipment, DCOSS version 5.10.

DCOSS is a key simulating equipment used by telecommunications network engineers. Typical applications of DCOSS include:

• Testing switches, gateways, and networks using a variety of signaling protocols. These available protocols include T1/E1 CAS, PRI ISDN, SS7, and SS5.
• Simulating traffic and analyzing traffic.
• Voice Quality Testing using PAMS, PSQM, PSQM Plus, and PESQ.
• Real-Time FAX Call Generation/Reception (V.29, V.27, V.17, V.33).
• Send/Receive Modem Traffic (V.21, V.23, V.34, V.90, V.92).
• Transmit and Detect Tones (Single/Dual), and Digits (DTMF/MF).

The features in DCOSS version 5.10 as announced today include,

• Simultaneous Transmission/Reception of voice files: DCOSS version 5.10 now allows simultaneous transmission/reception of audio data. This new feature is available with Manual Calling, Bulk Calling, and Bulk Call scripting functions.
  
  
• Remote Client Access: DCOSS Remote Client feature has now been enhanced to allow users to stream audio files currently located on the DCOSS server to the remote clients' speakers. It provides user-friendly interface to explore the directories of the DCOSS server and remote clients, allowing users to easily load or save data at the desired location.
  
  
• Remote Server Control: DCOSS has been enhanced to support Remote Access Server (RAS) functionality using a Modem. It can be configured to perform RAS functionalities with just a single timeslot or, if desired, the same functions can be configured to utilize up to 96 timeslots simultaneously.
  
  
• Additions in Signaling System 7: Initial Address Message (IAM) has been enhanced to support Redirecting Number and Redirection Information. Also added is the ability to manually generate CPG messages within an established SS7 call.
  
  
• Event Logging in Resource Management: DCOSS 5.10 now provides additional logging capabilities by allowing user to automatically capture events to user-defined text files. This information can be saved and later loaded (using Master Configuration) for quick access.
  
  
• Support for additional Protocols: DCOSS is enhanced to support Australian MFC-R2 as an addition to the E1 MFCR2 protocol variants.
  
  
• Hardware support: The new additions in the DCOSS hardware are,
  
  
  • DET002 and DET004 (software selectable dual/quad T1/E1 digital trunk boards).
  • DR040TE (4 link SS7 board with software selectable dual T1/E1 trunks).
  • DR050TE (16 link SS7 board with software selectable dual T1/E1 trunks).

  Boards no longer supported by the DCOSS include:
  
  

  • ISA SS7 board
  • ISA 8/24 Port Analog Station card
  • GR-303 board
  • BRI-U Interface board
  
  
• Enhancements in Scripting and Switch-routing: The switch routing now includes options for the user to add a prefix, an extension or change the called/calling numbers during a switch call operation as required. Further, the enhanced scripting features in DCOSS allow auto manipulation of the parameters within the script functions.
  
  

In addition to the above enhancements, there have been many other minor enhancements and bug fixes to the earlier version of DCOSS. Please visit DCOSS page for further details.
