Addressing the press conference, Mr. Rob Bichefsky, Senior Manager of Product Development at GL said, “The BRI Phone Simulator (BPS) converts GL's DCOSS into a BRI ISDN Terminal Phone Simulator. The BPS can simulate a bank of up to 128 BRI telephones (terminal side), each supporting one D-channel and two B-channels. Using a basic DCOSS with E1 PRI ISDN trunks along with a BPS external box, the DCOSS BPS may be used to test a BRI Network”. He added, “All functionality currently associated with the DCOSS, including bulk calling, scripting, and remote client/server, may be used to control the BPS external ports. Also, all traffic supported by the DCOSS (Fax, Modem, Voice Files, DTMF/MF Digits, and Frequency Tones) is also fully supported by the DCOSS BPS device”.
Mr. Rob Bichefsky further added, “The DCOSS connects to the BPS via a PRI ISDN E1 trunk and calls are generated to the BPS using the DCOSS GUI. Each digital call signifies BRI Phone off hook with DTMF/MF dialed digits from the BPS. Both outgoing and incoming BRI calls are supported. The connection to the BPS is via a standard RJ-45. Each of the BRI Digital ports (up to 8 per BPS, maximum of 128 ports per DCOSS system) serve as an independent BRI telephone, which can be individually configured and activated for various telephony tasks”.
• Connecting with a BRI Network, the DCOSS BRI Phone Simulator (BPS) supports up to 128 BRI Digital telephones per DCOSS system, 1 D-Channel + 2 B-Channels;
• Voice, FAX and Modem Call Generation and Reception;
• DTMF/MF Generation and Detection;
• Single/Dual Frequency Tones Generation and Detection and so on.
DCOSS APS (Analog Phone Simulator)
The DCOSS APS (Analog Phone Simulator) converts a GL DCOSS into an analog phone simulator that simulates a bank of up to 384 analog telephones. Using a basic DCOSS with T1 trunks along with the APSCB24/48 external boxes, the DCOSS APS may be used to test a Central Office (CO), PBX, Gateway, or other telecommunications equipment, which provide local loop interfaces.
About GL Communications, Inc.
Founded in 1986, GL Communications, Inc. (gl.com) is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards and solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (HDLC, ISDN, SS7, CAS, GSM, GPRS, CDMA), and with capacities up to thousands of channels.
GL’s VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones, noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs. Additional features include visual analysis, real-time listening, recording, and voice quality assessment using ITU algorithms PAMS, PSQM, and PESQ.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and CDMA 2000 networks. Connections can be made to any wireless phone with automated call control, GPS, mapping software, and real-time signal measurements.
GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160.
GL’s Network Surveillance and Monitoring products include Probes for TDM, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
