ADTRAN 1202843E1 Octal T1 E1 Wide Network Module

ADTRAN NetVanta Octal T1/E1 Wide Module (P/N 1202843E1) is an eight-port expansion card that plugs into the NetVanta line to deliver eight T1 or E1 circuits in a single wide module. This RoHS-compliant module is designed for use with NetVanta 4305 and 5305 routers, expanding carrier-grade WAN connectivity in branch-office deployments. In official NetVanta hardware documentation, this model is listed as the "Octal T1/E1 Wide Module" (P/N 1202843E1), and ADTRAN's product catalog also describes it as "OCTAL T1/E1, 2ND GEN T" in prior price lists. The octal designation indicates eight T1/E1 channels that can be configured for multiple WAN connections, enabling scalable aggregation of leased lines or service handoffs on supported NetVanta platforms. This module is positioned within the NetVanta wide module family, intended to augment the router's interface density without occupying additional chassis slots beyond the expansion slot. Typical deployments include small to mid-size enterprises needing multiple T1 or E1 interfaces for unified WAN failover, load sharing, or primary-secondary link configurations, all managed through the NetVanta management suite. The product's RoHS compliance and the explicit compatibility notes help buyers verify suitability for existing NetVanta 4305 or 5305 installations and ensure proper installation within supported chassis.
