X.25 PORT CONFIGURATION
Summary:
Use this procedure to set several parameters that must be set before using the X.25
interface. Table 558-1, Table 558-2, and Table 558-3 outline the X.25 interface parameters and
detailed technical specifications that are supported by the Soneplex Broadband system.
Data Link Layer LAPB Parameters
The Soneplex Broadband system data link layer uses the standard Link Access Procedure Balanced
(LAPB) protocol. Parameters supported, set values, configurable options, and defaults are shown in
Table 558-1.
Network Layer X.25 Packet Parameters
The Soneplex Broadband system now supports three Virtual Circuits, including two Permanent
Virtual Circuits (PVCs) (each assigned to a separate TL1 or Craft interface), and one Switched
Virtual Circuit (SVC). The X.25 interface operates only on Port 3. The PVC ID default
assignments are shown in Table 558-2.
Other Network Parameters
Other supported network parameters, set values, configurable options, and defaults are shown in
Table 558-3.

Edits can be made in the configuration database in one of two ways: 1) If the
complete field is highlighted, use the space bar to toggle forward or the “R” key to
