The CISCO VIC-2E/M supports both Type I and Type V E&M signaling, making it versatile for different network configurations and allowing smooth communication between PBXs or other telephone equipment. This card is an excellent choice for enterprises looking to expand their telephony capabilities while ensuring compatibility with existing E&M signaling equipment.
