Voice interface card - plug-in module / 2 analog port(s) - refurbished
Cisco 2600 and 3600 low density voice/fax network modules provide enterprises, managed service providers and service providers the ability to directly connect the PSTN and legacy telephony equipment to existing Cisco 2600 and Cisco 3600 routers. This provides immediate multiservice advantages, such as telephony toll bypass, new packet telephony applications, and full gateway integration within a Cisco AVVID architecture. The low-density voice/fax network modules for the Cisco 2600 and Cisco 3600 series multiservice access routers enable packet voice technologies including VoIP, VoFR and VoATM (AAL5). Cisco voice solutions provide the means for integrating both voice and data within a single network allowing users to take advantage of services, such as toll-bypass, without sacrificing voice quality. This combination of voice solutions leverages Cisco's proven track record of being able to effectively handle time-sensitive traffic over IP networks. The low density voice/fax network modules slide into Cisco 2600 and 3600 network module slots and contain either one or two voice interface card (VIC) slots. The VICs are daughter cards that slide into the voice/fax network modules and provide the interface to the telephony equipment and the PSTN. Just as the Cisco WAN interface cards can be swapped with other WAN interface cards, the Cisco VICs can be deployed interchangeably with other VICs in the voice/fax network modules. VICs currently available include two-port foreign exchange station (FXS), foreign exchange office (FXO), and E&M analog interface cards.
