Q: Who are your potential customers?
A: Our largest potential customers are service providers both at the retail level and the carrier-of-carriers level who own or lease their own fiber. This includes local telephone companies, IXCs, RBOCs, PTTs, CLECs and cable TV operators (MSOs). However, we also have a number of System Integrators (SIs), and reseller agreements. Our Ethernet based ExpressSTREAM and ATM based ExpressFLOW™ product lines are designed to address the multi-point broadband needs of all access service providers. Our ExpressRING™ and ExpressSTREAM XE Ethernet product lines are designed for access/extension links for service providers as well as for customers wanting to create their own private network.

Q: Why does Nayna Networks think it has an excellent opportunity moving forward?
A: First of all, carriers overbuilt their backbone networks, this in turn caused an urgency to fill underutilized backbone capacity with revenue generating bandwidth. Backbone bandwidth must come from and then be terminated by the revenue generating access network. Nayna solutions provide the entrance ramps bringing retail subscriber traffic on to the backbone network. Thus, the access segment has very high near term opportunities compared to the overall telecom market. Secondly, Nayna Networks new Ethernet in the First Mile (EFM) based ExpressSTREAM product line eliminates many ATM conversions for a lower total cost structure. The ExpressSTREAM platform is very robust and is designed to support very demanding new applications such as streaming video over Ethernet.

Q: Does Nayna support Passive Optical Network (PON) technology?
A:Actually, Nayna was the first to bring IEEE802.3ah compliant gigabit Ethernet PON (EPON) to the market in our ExpressSTREAM platform, which also supports equally well gigabit Ethernet Point-to-Point technology. Likewise our ExpressFLOW platform was one of the first ITU G.983 compliant ATM PON (APON) platforms. At Nayna we proud that our EPON can share a single common fiber up to 127 sites, which results in a dramatic cost reduction for the service provider.

Q:What is the secret to the success of the ExpressSTREAM EFM platform?
A: ExpressSTREAM offers (1) ATM quality at an Ethernet price, (2) incredible performance, and (3) topology flexibility.

More than 80% of the traffic today comes in the combination of Ethernet and IP. By eliminating ATM conversions we are able to bring Ethernet's price advantages to the broadband market. ExpressSTREAM can handle up to 32 Gbps of Ethernet traffic without blocking for a significantly lower price/bit ratio. Whereas traditional ATM access equipment would only handle 155 Mbps, 622 Mbps or at the most 2.5 Gbps. By supporting point-to-point and multi-point PON technology in the same platform, ExpressSTREAM offers a complete range of solutions for all types of network layout topologies - plug & play regardless of the existing physical fiber layout.

Q: What kinds of products compete with NAYNA EXPRESS™ solutions?
A: OThere are 2 major types of competitors: The first type of competitor comes from the copper equipment vendors who are laboring under the inability to increase their bandwidth delivery enough to ensure service providers with a future proof network. The second type of competitor comes from classical legacy TDM equipment vendors. However, they lack the basic product design to carry themselves forward in the new era where data makes up most of the traffic. NAYNA ExpressSTREAM platforms offer both copper and fiber interfaces are designed to handle many gigabits of data traffic along with TDM traffic to ensure long-term deployments with carriers.

Q: What is the secret to the success of the ExpressRING R310?
A: Actually, there three secrets behind the R310. The first is a blazing fast <10 ms switch over time in case of a fault. This is much faster than competing solutions, including SDH/SONET that typically take upwards of 50ms. The faster switching time reduces the cost of lost traffic, and makes the R310 ideal for mission critical applications. The second is guaranteed quality of service (QoS) required for real time services including video surveillance, POTS, and T1/E1. The third secret behind the success of the R310 is our unique Auto-Learning Dynamic Bandwidth Allocation (AL-DBA). AL-DBA provides much better Ethernet performance, which can in some cases be as high as 100 Mbps better than traditional fixed bandwidth allocation methods.

Technical Implementation 

Q: What makes Nayna ExpressStream platform unique?
A: Heavy duty carrier class construction that support huge demand flows from stream media (music and video) that will not drop packets due to strong Quality of Service (QoS) features such as broadcasting and VLAN tagging, ingress rate control and egress rate control.

Q: How many fiber circuits do NAYNA EXPRESS solution support?
A: The ExpressSTREAM supports up to 24 PONs each with up to 127 sites, and 144 point-to-point circuits per 19" chassis. ExpressSTREAM support 1:N redundancy. The ExpressFLOW X9000 and X9500 support up to 4 PONs and 4 additional redundant PON circuits. The ExpressRING R310 supports one fiber strand operation and also supports dual-fiber for redundant counter rotating rings.

Q: What does your headend rack density look like?
A: Clearly rack density reflects real estate costs of the CO (Central Office) required to house the gateway. In our case, with the ExpressSTREAM XC120000 chassis up to seven systems can be mounted in a rack.Three ExpressFLOW chassis may be mounted in a rack. The ExpressRING R10 uses just two rack units 20 can be placed in a rack.

Q: How does NAYNA EXPRESS secure the software management systems?
A: Our network management software systems allow multiple levels of passwords and privileges. The security architecture makes it possible to have some read-only users while the main network administrator has full read/write privileges. In addition, each node has a unique identification number and is not allowed on the network without first being approved by the network administrator.

Q: I have heard the NAYNA EXPRESS solutions also include IP video (IP-video), Digital Video Broadcasting (DVB-C) support, analog (RF QAM), CATV support and (RF QAM) satellite TV support? Would you please explain your video support to me?
A: Yes, we support all options for all four types of video. Our products are designed to support a variety of topologies including bus, star, tree and ring. The tree topology is very common with existing analog and digital CATV service providers so it is natural for us to also add video and TV support. Both analog and digital video signals travel down the fiber and thus retain high quality levels. For satellite TV we handle up to 2.1 gigahertz. For digital TV we use DVB-C compatible Transport Streams (TS) over our single fiber network, the digital TV signal is kept in its native digitally encoded format and brought very close to the customer before it is converted into an analog format by the set-top-box. For the newest video transport method, IP-video over Ethernet, we use Virtual LAN (VLAN) tagging to separate priorities while running the real time video stream over gigabit links to the terminating optical node.
