Voice

As carrier networks evolve, GPON systems must handle legacy traffic, such as T1 and E1 circuits. This requires a solution that is standards-based, has standard-compliant clock recovery, and can offer service for different TDM modes.  iPhotonix has long been the leader in Voice services over GPON/PON.  Whether it’s traditional TDM (Time Division Multiplexing) or support for SIP, MGCP and& H.248, iPhotonix continues to be leader in this space.  Our experience with packet voice, a large number of softswitch interoperabilities and multiple protocols makes our Universal Access Software the most compatible system software in the market today.  As traditional voice revenues fall, carriers need to be sharp and pick the right technology combined with the right supplier to leverage their existing assets. 

The iPhotonix Universal Access Software provides a seamless transition from TDM circuit to the next-generation packet-switched networks.  In this initial transition phase from time-division multplexing (TDM) to a packet network, timing over the physical layer is not available (e.g., equipment not supporting synchronous Ethernet or physical limitations across administrative domains), the distribution of timing via packets-based solutions  (e.g., (Precision Time Protocol or PTP PTP/ IEEE 1588) is seen as an alternative option.  iPhotonix continues to advance its timing solutions for Packet-based networks making the evolutionary step for operators seamless migration. IEEE 1588/PTP (also known as Precision Time Protocol or PTP) is the emerging standard for providing precise timing and synchronization over packet-based, Ethernet networks.  iPhotonix provides solutions that enable  our customers to directly benefit from lower-cost, higher-capacity packet-over-Ethernet network infrastructures without sacrificing precise timing and synchronization requirements.

IEEE 1588 PTP Solutions

Ethernet and IP are rapidly replacing traditional TDM circuit infrastructure creating "timing islands" in the network, potentially causing service impairments. Mobile services are especially vulnerable as they require precise synchronization at base stations.  iPhotonix will deliver via 1588 synchronization in the packet network. With our capability to provide traditional TDM T1/E1 services via pseudo wire and include 1588 clocking on the GE Ports on the same ONT, iPhotonix can supply great options for Cellular backhaul solutions as the cellular architecture transitions to a packet network.
