Avaya 700394612 C-LAN Interface Circuit Pack TN799DP for Communication Manager systems.

The Avaya 700394612 is a C-LAN (Control LAN) Interface Circuit Pack, model TN799DP. This card provides Ethernet connectivity for IP-based communication between the Avaya Communication Manager server and IP endpoints, media gateways, and adjunct systems. The C-LAN interface handles signalling and control traffic essential for VoIP call processing.

The TN799DP is designed for installation in Avaya G650, G450, and other compatible media gateways within Avaya Aura and legacy Communication Manager environments. It serves as a critical component for IP telephony deployments, enabling the gateway to communicate with H.323 and SIP endpoints across the enterprise network.

This is a legacy circuit pack from Avaya’s established Communication Manager platform. While superseded by newer Avaya Aura Session Manager architectures, the TN799DP remains in active use across many enterprise telephony installations requiring maintenance or expansion of existing systems.
