Solution : tProbe™ + SonetExpert™ + T3/E3 Analyzer

Physical Layer Analysis

Physical Layer Analysis is used to monitor T3 E3 and T1 E1 line alarms. The analyzer helps to track the time at which alarms (Sync Loss, Carrier Loss, Remote, Distance MF, AIS) occurrs and periodically send these information to either centralized database such as Oracle DB, or send traps to SNMP monitoring applications.

GL’s NetSurveryorWeb™ accesses fetches the records from the central database and facilitates the user to monitor physical layer status of T1 E1 line via simple web based clients. For more details, refer to Network Line Monitor and Test

Supported T1 E1 Alarms

Line Sync Loss: This alarm indication will flash when a receiver resync is in progress. If the receiver is set to auto resync in the Configuration Menu, the receiver will begin resync when an OOF (Out Of Frame) event or Loss of Carrier is detected.

Carrier Loss: Carrier loss alarm is declared when 128 ± 1 consecutive zero's are detected. Carrier loss clears when a ‘1’ is received.

Remote Alarm Detected (E1 Only): This alarm indication will flash when a remote alarm is detected. A remote alarm is defined as the reception of three consecutive bits equal to ‘1’ of timeslot 0 of non-align frames.

Distant Multiframe (MF) (E1 Only): This alarm indication will flash when a distant multiframe alarm is detected. A distant multiframe alarm is defined as the reception of three consecutive 1s at bit position of timeslot 16 in frame 0. This indication is only valid when in CAS mode.

Alarm Indication Signal (AIS): The receiver detects an AIS pattern when it receives less than three zeroes in any string of 2048 bits.  The AIS condition is cleared when three or more zeros are detected in 2048 bits.

Supported T3 E3 Alarms

Loss of Signal (“LOS”) : This is the most basic of all alarms.  No signal is present.  Usually this means that the cable is broken or disconnected, or that the remote device is out of service.  No other alarms are meaningful when LOS is present.  In the T1 E1 Analyzer, this alarm is referred to as “Carrier Loss”.
In the software Rx Framers, an all-0 signal is interpreted as Loss of Signal.

Loss of Frame Alignment (“LOFA”) : LOFA is also known as “Out-of-Frame” (“OOF”) or “Sync Loss”, a signal is present but the Rx Framer is unable to synchronize with the incoming multiframes.  This usually means that either the framing strategies are incompatible (E1 T1 mismatch, DE4/ESF mismatch, etc.), or the signal is so poor that frame sync cannot be reliably established.  It may also mean that the receiving equipment is expecting CRC but the sending equipment is not transmitting CRC.  In the T1/E1 Analyzer, this alarm is referred to as “Sync Loss”.

Alarm Indication Signal (“AIS”) : In the T1 world, this is referred to as “Blue Alarm”.  In the E1 world, it is referred to as “AIS”.  The AIS/Blue Alarm signal is an unframed all-1s bit pattern.  Note that a framer receiving a blue alarm will lose frame sync, and will raise a red alarm if the condition persists for more than 2.5 seconds, since the basic frame synchronization signal contains zeros.

Idle : This alarm becomes active upon reception of the T3 Idle signal. Idle alarm indicates that the line has not been provisioned for service and stays without triggering network alarms.

Remote Alarm Indication (“RAI”) : In the T1 world, this is referred to as “Yellow Alarm”. In the E1 world, it is known as “Remote Alarm Indication” or “RAI”.  A device in red alarm at its receiver must transmit yellow alarm/RAI back to the sending device, alerting it that the receiving device cannot synchronize with the signal being sent.  We got this one right on our T1/E1 Analyzer alarm dialogs.

Excessive 0’s : An EXZ occurrence is defined as three or more consecutive zeros in the T3 mode and four or more consecutive zeros in the E3 mode.

Sending SNMP Traps from Physical Layer Analyzer

Physical Layer Analyzer can send SNMP traps to one or more SNMP notification receivers.

Physical Layer Analyzers continuously captures alarms on T3 E3 and T1 E1 ports. Physical Layer Analyzer sends SNMP traps when alarm status changes to SNMP monitoring applications specified by an IP Address and a UDP port.

SNMP traps data are monitored at NOC using any SNMP Monitoring Application as shown below.

DSU Subrate Configuration

Subrate allows DSU manufacturers to control bandwidth from service provider end and sell user specific bandwidth. USB T3 E3 Analyzer supports DSU DS3 Subrate configuration for Digital Link, Larscom, Verilink, and Adtran as shown in the figure.

For more details refer to T3 (DS3) Subrate and Scrambling webpage.

Bit Error Rate Test (BERT)

GL's T3 E3 Bit Error Rate Tester application measures the correctness of data received on T3 E3 channels for a repetitive fixed or pseudorandom pattern for the given transmission. BERT provides a figurative measurement of the number of erroneous bits received for the total number of bits transmitted.

GL’s USB T3 E3 BERT Windows Client Server task (BWT) implements the functionality of the Enhanced BERT GUI application for T3 E3 WCS Server. T3 E3 WCS commands is used to setup all ports to unstructured mode and all framing formats such as unframed, M13, E13, and C-bit. BERT can be run and tested on all framing formats.

Working Principle

The T3 E3 hardware platform with associated T1 E1 Send/Receive Server and Channelized T3 E3 analyzer software can generate, capture, record, and monitor multiple T1 or E1 channels over Channelized T3 E3 links. It can perform analysis of various signal types including voice, digits, tones, fax, modem, and raw data.

The Channelized T3 E3 to T1 E1 solution, comprises of two modules, namely, the High-Speed T3 E3, and Low-Speed T1 E1 modules. These two modules are actually two separate processes running on the same computer. The High-Speed T3 E3 process is called as T1 E1 Send/Receive Server, as the name suggests it runs as a service and works with USB T3 E3 hardware. The Low-Speed T1 E1 module part is referred to as Channelized T3 E3 analyzer software.

The T1 E1 Receive Server application within USB T3 E3 analyzer acts as software-based Multiplexer- Demultiplexer application capable of channelization of a T3 signal into 56 independent T1 channels and an E3 signal into 32 E1 channels. The channelized streams containing T1 E1 frames are forwarded to T3 E3 Channelized T1 E1 analyzer software over UDP using GL Message Protocol for analysing frames per channel.

ISDN Analysis over T3 E3 Signals (56 T1s)

Accompanying Basic Software/Features

Almost all the basic and optional monitoring applications supported by T1 E1 analyzers are also supported by Channelized T3 E3 T1 E1 analyzer. For example, capturing an entire T1 E1 signal, or performing ISDN, or SS7 analysis, can be performed using the software accompanying the Channelized T3 E3 T1 E1 analyzer.
