Positron Access Solutions 24 Document 180-0212-001 R02
Point-to-point and
Point-to-multipoint
Support
Point-to-point (coax)
Point-to-multipoint operation (coax) for up to 16 Subscriber CPEs per G.hn port
Supports firmware and configuration management of G.hn end-point devices
AES-128 encryption with individual keys for each End Point. The Positron GAM Domain
Master is also acting as the G.hn Security Controller
Modulation and
Frequency Band
Supports OFDM 200 MHz.
Radio Band Notching function allows cohabitation with legacy analog cable TV channels
on coax cabling
Up to 1.7 Gbps with Dynamic Bandwidth Allocation to optimize throughput based on
nature of traffic flows with TDD Multiplexing for programmable upstream / downstream
ratio
Reliability and
Resiliency
State of the art LDPC Forward Error Correction (FEC)
Spanning Tree Protocol
(STP)
Standard Spanning Tree 802.1d
Rapid Spanning Tree (RSTP) 802.1w
Multiple Spanning Tree (MSTP) 802.1s
Link Aggregation Control Protocol (LACP) IEEE 802.3ad for any SFP+ or G.hn ports
Supports up to 4K VLANs simultaneously (out of 4096 VLAN IDs)
• Port-based VLAN
• IEEE 802.1Q tag-based VLAN
• IEEE 802.1ad (Q-in-Q) double tag VLAN
• MAC-based VLAN
• Management VLAN
• Private VLAN Edge (PVE)
Generic VLAN
Registration (GVRP)
Protocols for automatically propagating and configuring VLANs in a Multicast Domain for
IPTV and other multicast services
IGMP limits bandwidth-intensive multicast traffic to only the requesters
Supports 1024 multicast groups
IGMP snooping with proxy reporting or report suppression actively filters IGMP packets to
reduce load on the multicast router
IGMP query is used to support layer-2 multicast domain in the absence of a multicast
router
Deliver IPv6 multicast packets only to the required receivers
Supports DHCP server to assign addresses to IPv4 client devices
DHCP snooping provides security by filtering un-trusted DHCP messages and by building
and maintaining a DHCP snooping binding table
By supporting DHCP option 82, it is possible to forward DHCP requests to another
specific DHCP server via DHCP relay. The DHCP server may be on another network
Static routing of IPv4 unicast traffic
Static routing of IPv6 unicast traffic
