- This instrument handles signalling, voice, and knowledge in complete T3 (DS3) or E3 streams, supporting seamless T1 (DS1) or E1 drop and insert.
- It excels in analysing numerous protocols like HDLC, ATM, Body Relay, and PPP, catering to Unchannelized (Unstructured) and Channelized (Structured) T3 E3 Visitors.
GL Communications Inc. introduces the T3 E3 Analyzer, designed for T3 and E3 community monitoring and visitors technology. It gives full management over constituent T1 and E1 strains, enabling evaluation and replication of telecom protocols like ISDN, CAS, and SS7 on T3 E3 networks. This versatile resolution manages signalling, voice, and knowledge in full T3 (DS3) or E3 knowledge streams, supporting seamless T1 (DS1) or E1 drop and insert. It affords an in-depth evaluation of protocols like HDLC, ATM, Body Relay, and PPP, making it appropriate for Unchannelized (Unstructured) and Channelized (Structured) T3 E3 Visitors.
A T3 line delivers spectacular knowledge transmission speeds of as much as 44.736 Mbps, whereas an E3 line, a part of the Plesiochronous Digital Hierarchy (PDH), operates at 34.368 Mbps. Due to the channelised characteristic of the T3 E3 Analyzer, it affords direct entry to all channels inside a T3 or E3 line, accommodating configurations reminiscent of 2×28 T1s, 2×21 E1s, or 2×16 E1s. This complete performance facilitates seamless emulation, evaluation, and monitoring on a single PC, masking numerous T1 or E1 framing codecs, bodily layer alarms, and payload examination. Furthermore, the T3 E3 {hardware} platform, in collaboration with the T1 E1 Ship Obtain Server and Channelized T3 analyser software program, can transmit T1 E1 frames over T3 E3 strains and concurrently seize, report, and monitor a number of T1 or E1 channels throughout Channelized T3 or E3 connections. This versatile system analyses numerous sign varieties, together with voice, digits, tones, fax, modem alerts, and uncooked knowledge. A few of its key options embody:
- Compact and light-weight evaluation platforms for T3 (DS3) and E3, that includes the power to seize twin knowledge streams.
- Supporting a variety of testing situations with a number of interfaces for evaluation, together with T3 (DS3)/E3 and T1 E1.
The software program affords selectable T3 (DS3) and E3 interfaces, together with T1 and E1 Drop and Insert capabilities. It helps twin T3 (DS3) / E3 receivers and transmitters for simultaneous non-intrusive and intrusive testing in eastbound and westbound instructions. The system affords versatile clocking choices, together with inner, recovered (from T3 E3, T1, or E1), and exterior sources. It additionally allows scripting and automation via GL’s Home windows Shopper Server (WCS) strategy, permitting for Python script integration on Home windows and Linux working methods. Moreover, it consists of an HDL File Conversion utility for changing between ethereal format information (*.pcap, *.cap, and *.pcapng) and GL’s file format (*.hdl) and vice versa.
Unchannelized and Channelized Testing
The testing capabilities of this method may be categorized into two primary modes: Unchannelized (Unstructured) Testing and Channelized (Structured) Testing. Within the Unchannelized (Unstructured) Testing mode, the system affords the pliability to conduct assessments with out predefined channels. It facilitates the evaluation and simulation of assorted protocols reminiscent of ATM, PPP, HDLC, and Body Relay. Customers may also ship and confirm HDLC frames with headers that they will customise. Furthermore, the system helps options like scrambling and subrate, making use of DSU distributors’ algorithms for the T3 interface, which incorporates distributors like Digital Hyperlink, Larscom, Verilink, and Adtran.
The Channelized (Structured) Testing mode gives a structured strategy to testing. It consists of beneficial drop and insert capabilities and makes use of the twin T1 E1 ports on the {hardware}. This mode permits for the multiplexing and de-multiplexing of T1 (DS1)/E1 alerts to allow drop and insert functionalities. It additionally helps bidirectional monitoring via twin T1 (DS1)/E1 drop, and the system can transmit both externally inserted or internally generated T1 or E1 streams into T3 (DS3)/E3 strains. Moreover, it may possibly conduct stress assessments on M13 (E13) multiplexers and three/1 Digital cross-connect methods. Moreover, it affords the pliability of dual-channel drop and insert of T1 or E1 alerts from any T3 (DS3)/E3 sign, together with choices for broadcasting or loopback of particular person T1s/E1s obtained from T3 (DS3)/E3.
Testing and Evaluation Capabilities
The system features a BIT Error Fee Take a look at (BERT) functionality for simultaneous T3 E3 channel testing via WCS instructions. It additionally incorporates Tx/Rx Server Software program, enabling T1 E1 body transmission over T3 E3 strains through the T1 E1 Transmit Server. The T1 E1 Obtain Server demultiplexes T3 E3 knowledge into T1 or E1 channels. This permits sending and receiving 28 T1 channels per port from a T3 sign, 21 E1 channels per port (G.747 Mapping) from a T3 sign, and 16 E1 channels from an E3 sign. The system allows monitoring of framed and unframed T1 E1 alerts (Rx Solely) and simultaneous evaluation of all 56 T1s (1.544 Mbps every) or 32 E1s (2.048 Mbps every). It gives evaluation capabilities for Fractional T1s and E1s, N x T1s or N x E1s, and any mixture of DS0s (64 kbps every) inside the T1s or E1s, totaling 1,344 DS0s for T1 or 1,024 DS0s for E1. Moreover, it helps Protocol Evaluation for all structured protocols, together with HDLC, ISDN, CAS, and extra, whereas monitoring T1 E1 alarms, payload, and framing construction.
