  To provide more than one level of suspension with PPP Multilink, one can run Multilinks multiple times over one link, which is commonly known as Multi-Class Extension to Multi-Link PPP (MC MLPPP). This allows sender to fragment the packets of various priorities into multiple classes of fragments. This Multi-Class Extension to Multi-Link PPP option is soon to be supported by GL's MLPPP Emulator.

  Bulk delay is an added feature in Error insertion application that allows users to apply Bulk delay on the entire T1/E1 trunk (full multi-frame) of 1.544Mbps (T1) pipe or 2.048 Mbps (E1) pipe. Delay can be varied from 0 to 169.77mS (T1) or 127.99mS (E1) with an accuracy of +/- 10uS. The delay resolution is based on the byte increments of T1 or E1 (8 bits at a time).

  • Adobe Audition software is automatically called and the files are displayed in stereo or mono mode depending on number of files selected. It supports a variety of file formats including *.pcm, A-Law, Mu-Law, *.wav, and others.

  • Goldwave software is automatically called and the single file selected is displayed in stereo mode. Selecting couple of files at a time acts as a single file displaying graph in stereo mode assuming one of the files as east and the other as west file.

• Called/Calling Number Configuration in ISDN Emulator

  This feature permits users to set the called and calling numbers on corresponding timeslots. The following parameters are included

  • ISDN Sub-address - this is used to address each device, when more ISDN devices use the same line. The sub-address is a sequence of digits, the maximum length of which is 20 octets.

  • Calling party sub-address (Q.931 setup) - the purpose of this information element is to identify a sub-address associated with the origin of a call.

  • Called party sub-address (Q.931 setup) - this information element serves to identify the sub-address of the called party of the call.

This is especially useful in applications such as Isdn Emulator where Profile Loading/Saving capability from command line can be used to automatically place a call on a timeslot without any user intervention. The Load Profile feature is also now supported for Windows Client Server.
  
  
• Call Capture & Analysis (CCA): This application now includes the ability to set triggering to capture calls when any SS7 signaling messages are received. Call filtering with user-defined called and calling numbers can be filtered out apart from the normal working of capturing all the calls.
