Star India has continued its vexing policy to challenge and stall every TRAI order through a court of law. Last month, they challenged the TRAI's proposed draft tariff order even before it was formulised and declared! The TRAI was in fact responding to instructions ..........
NETLINK OLT & ONU
In an internet / broadband distribution network, an OLT (Optical Line Termination) unit is located at the Control room / headend and receives electrical data signals and converts them to optical output signals. Loosely speaking, its function is like a CATV Fibre Optic transmitter.
The Netlink NL7008B OLT which provides 8 x Giga Ethernet (copper) ports + 8 SFP slots independent optical interface for uplink, and 8 EPON OLT ports for downstream. It can support 512 ONUs with a 1:64 splitter ratio.
The built-in OLT management functions include Fan Group Detection, Port Status monitoring & configuration management; Layer2 switch configuration such as VLAN, Trunk, RSTP, IGMP, QOS, etc. EPON management functions include DBA, ONU online configuration and management; ACL, QOS, etc;
Its Layer2 Switch provides extensive VLAN support, as well as support for IEEE802.3d trunk & RSTP, IGMP Snooping as well as IEEE802.x flow control and Port stability monitoring.
The unit fits in a 1U 19-inch rack, and consumes 45 Watts. it is priced at Rs. 75,000 + Tax.
An Optical Network Unit (ONU) converts optical signals transmitted to it via fiber, to electrical signals, for a broadband network. Its function and location are similar to a Cable TV optical node, in a cable TV network. These electrical data signals are then sent to individual subscribers.
Utilising a Hisilicon / Realtek chip, the TE-R1P1G-OU ONU provides symmetric 1.25 Gbps speed.
Special features include: Plug and play, auto-detecting, auto-configuration & auto firmware upgrade; OAM remote configuration & maintenance; QinQ VLAN functions and IGMP Snooping multicast.
The Netlink TE-R1P1G-OU is fully compatible with OLTs based on Broadcom/PMC/Cortina chipsets.
Power consumption is only 3 Watts & is priced at Rs. 1,400 + Taxes.

MAIPU GIGABIT ACCESS SWITCH
Given India's rapidly growing Broadband industry, Maipu has launched a Compact sized, 8 port x 1 Gigabit access switches & the 4 port x 1 Gigabit cooper access switches.
MyPower S3200 series switches provide perfect solutions in the aspects of multi-service capability, security, reliability, management and maintenance. It is the idle access device of the industry users and carriers. It has powerful multicast and QoS capability, meeting the real-time requirements of the enterprise network video, audio data and other high-priority services.
The Small Form-factor Pluggable (SFP) switch is ideal for use in a Broadband Ring network and access delivery, providing a throughput of upto 24 Gbps.
Its key features include:
♣ RSTP (Rapid Spanning-Tree Protocol),
♣ MSTP (Multiple Spanning Trees Protocol)
♣ ACL (Access Control List)
♣ CPU & Surge protection
♣ Bandwidth control Policies
With this new switch, ISP's and Operators can easily deploy Compact switches & achieve higher reliability in their network with multiple Ring networks from the same switch.
Maipu's 3200-12TC-AC switch is a fully L2 Manageable switch, with a complete feature set for Carrier switches. It is already being used my major Indian telecom companies for their 1 Gig ring networks.
The 3200-12TC-AC switch is priced at Rs. 12,000.
