– Key Features
Protocol Support
SS7 (MTP2 and ATM SS7), LAPB/D/V5, Frame Relay, X.25, HDLC, and Integrated Time Division Multiplexing (I-TDM) for traditional TDM SS7, high-speed ATM SS7, and voice interworking applications.
Processing & Throughput
On-board processor with minimal host load delivers high-capacity data throughput. Dynamically configurable channel allocation optimizes resource utilization for mixed protocol deployments.
Software Portability
Common software driver and unified API across PMC, AMC, PCI, and PCIe form factors. Single-driver architecture reduces development cycles and protects software investment across platform variants.
– Typical Applications
Traditional TDM signaling, high-speed ATM-based protocol stacks, voice interworking between legacy and modern network elements, Frame Relay and X.25 packet transport, multi-protocol convergence systems.
– Compatibility & Integration
Designed for scalable, flexible deployment across diverse system architectures. Form-factor independence via unified API enables rapid porting between embedded, modular, and standard computing platforms without application rewrite.
