If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. Only one BRI port would be active, and ISDN voice calls may not work if the card is installed in slot 1 of the NM-2V card. This is necessary to ensure that the NM-2V voice carrier card allocates the four Digital Signal Processor (DSP) resources correctly to the four available B channels on the two BRI ports. The second VIC slot of the NM-2V must not have any other VICs installed when an ISDN voice card is installed. The VIC-2BRI-NT/TE card should be installed in slot 0 of the NM-2V voice carrier card. The VIC-2BRI-NT/TE, supported on these hardware platforms: The information in this document is based on these software and hardware versions:Ĭisco 2610 router with an NM-2V voice carrier card. There are no specific requirements for this document. You can find comparisons between the VIC-2BRI-NT/TE and VIC2-2BRI-NT/TE in Understanding ISDN BRI Voice Interface Cards. Note: There is a new generation Voice Interface Card (VIC), called the VIC2-2BRI-NT/TE, which is a hardware refresh of an older card with similar functionality. Based on this, there are two types of cables, Straight and Crossover.This document details the configuration and cabling required to connect VIC-2BRI-NT/TE and VIC-2BRI-S/T cards as ISDN network devices. A cable may have the same or different standard connector at its end. Read similar articles: What is RJ45 Connector? Types of Ethernet CableĪs already mentioned above, the connector comes in two standards, T568A and T568B. The pinout description with the color code of T568B is given in the table below. It is backward compatible with only a one-pair USOC wiring scheme. It also isolates the signal more effectively as compared to T568A. T568B standard is a widely used wiring standard in current Ethernet applications as it gives better protection from noise. ![]()
