... flexible with programmable hardware that supports remote, in-service upgrades. Implementation of standards-based X.86 and Generic Framing Procedure (GFP) encapsulation ensures vendor interoperability and the ability to adapt as specifications change and evolve. Where applicable, Virtual Concatenation ...

... between institutions * Use of much lower-cost Ethernet interfaces for connecting routers and switches to the optical network * GbE and 10GbE with GFP, VCAT and LCAS supported in lieu of legacy POS * Realize more efficient utilization of network resources and reduction in ports via greater levels of ...

... also leverage CoreDirector's Ethernet capabilities offered by the platform's Ethernet Services Line Module (ESLM) to ensure interoperability of its GFP-encapsulated data with third-party platforms. MAX will employ the ESLM 10-Gigabit Ethernet (GbE) LAN PHY over SONET/SDH capability to provide 10 GbE ...

... Ethernet Line Module (GELM). The ESLM maps Ethernet packets to SONET/SDH frames using industry-standard mechanisms: Generic Framing Procedure (GFP), Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS). This module supports 10 x GbE or 1 x 10GbE ports and up to 64 SONET/SDH Virtual ...
