Features
GENERAL DESCRIPTIONw
Powered by the GigaPASS architecture, the GPON PAS6211 System On a
Chip (SOC) implements an FSAN-compliant ITU-T G.984 solution with
guaranteed 2.5 Gbit/s downstream, 1.25 Gbit/s upstream line-rate
operation. The device includes a GPON MAC, a packet processor, and an
ARM9 processor for voice application hosting and ONT management. A
complete ONT software suite compatible with multiple operating
systems is provided along with development tools to allow extensions
to the base software for application flexibility.
PRODUCT BENEFITS
- Full FSAN ITU-T G.984 GPON ONT functionality on highly-integrated SOC
- AES-128 decryption and FEC with GEM encapsulation for efficient,
reliable transport of Ethernet packets
- Integrated SERDES/CDR for 2.5/1.25 Gbit/s GPON transceiver
interface
- Sustained throughput of up to 1 Gbit/s upstream and downstream at
10/100/1000 UNI interface
- Advanced packet processing engine for flexible traffic mapping of
GEM Port-IDs to CoS T-CONTs
- Multiple filtering modes, VLAN processing options, and priority
classifiers for powerful traffic management with multiple SLAs
- Multicast flow handling using IGMP and MLD supporting IPv4 and
IPv6 for IPTV and broadband subscriber services
|
- Integrated ARM9 processor for control plane operations
- Native TDM support with TDM over GEM
- Open software development platform with support for Linux and
VxWorks
- Full ONU software development package including management
software, ITU-T G.984.4 MIBs, PLOAM, and OMCI to reduce
development time
- Host processor for support of SIP stacks, call processing, and VOIP
application software
- Support of T1/E1 over PWE3 for business applications
- Triple Play solution with powerful Ethernet engine, VOIP protocol
processor, and flexible Port-ID mapping based on 802.1p, 802.1q
|
