About Subscriber IDs Your FRX and SmartSwitch 1800 devices are designed to provide point-to-point dedicated connections among the devices communicating through their serial ports. There are two types of connections used to accomplish this: Permanent Virtual Circuits, or PVCs, which de.ne permanent point-to-point connections which are always available, even when they are not being used; and Switched Virtual Circuits, or SVCs, which are established and broken in response to speci.c call requests.

Octets The total octets received from or transmitted to an adjacent SDLC link station since link station startup, expressed as a rate (octets/second). This includes the address, control, and information .eld of I-frames only. Retransmits In the Rx Statistics window, this is the total number of I-frames retransmitted by the remote link station because the N(s) received from that link station indicated that one or more I-frames sent by or to that station were lost. In the Tx Statistics window, thi

A more negative setting produces a higher input gain (i.e., 7 produces the least input gain and -22 produces the highest input gain). If the In level is reduced (made more negative), the voice channel will be more sensitive to the input; this will cause the voice output at the remote device to sound louder. The default value for this parameter is 0. Level Out This parameter speci.es the local voice level out of the voice port. A more positive setting produces a higher volume (i.e., 7 produces th
