Cisco VCO/4K Open Programmable Switches

This document applies to the following hardware and software components:

• Virtual Central Office (VCO) and Specialty Digital Switch (SDS) platforms

• All VCO generic versions V5.0.x and later

A. Check the Extended Operation Mode Set field on the System Feature Configuration screen (Main Menu > System Config > System Feature Configuration). If it is set to Y, VCO is running in the extended mode. If it is set to N, VCO is running in the standard mode.

A. When the extended operation mode is enabled on the VCO, you must use the extended API. When the extended operation mode is disabled, you must use the standard API.

A. Yes. As long as you enable the extended operation mode on the VCO and do not need to access any port address above 0x7FF (2K range), you can use the extended API with the C-Bus disabled.

A. Yes. To access ports on the C-Bus (above 0x7FF), you must enable the extended operation mode.

A. No. With the standard API, you are restricted to port address 0x7FF (2K range). You must use the extended API to access ports up to 0xFFF (4K range).

A. To configure your VCO system for accessing 4096 ports, you must enable both the C-Bus and the extended operation mode (set to Y).

A. Boot the system with VCO Installation Disk 1 and follow the menu options to enable these modes.

A. In the extended operation mode, you have more virtual ports and can define more resource groups, inpulse, and outpulse rules compared to the standard operation mode (for more information, refer to the following question).

A. The standard mode supports 256 (port addresses 0x8000-0x80FF) virtual ports. The extended mode supports 999 (port addresses 0x8000 - 0x83E6) virtual ports.

A. In the standard mode, you can define up to 63 resource groups. In the extended operation mode, you can define up to 224 resource groups.

A. In the standard operational mode, each resource group can have a maximum of 256 members or ports. The extended operation mode supports a maximum of 1920 members or ports per resource group.

A. In the standard mode, you can define up to 30 inpulse rules compared to the extended operation mode, which supports up to 255 inpulse rules.

A. In the standard operation mode, you can define up to 30 outpulse rules compared to the extended operation mode, which supports up to 255 outpulse rules.

A. No, the VCO mode does not affect the SS7 subsystem. When the TCP/IP link between the VCO and the SS7 subsystem is established, the VCO sends a $DC report that is analyzed by the SS7/CktInt to determine the VCO's operational mode. The VCO then formats its commands and reports accordingly.

A. This depends on the VCO to which the SS7 is connected. If the C-Bus is enabled on the VCO, you need to run the 2Kto4K Configurator on the SS7.
