Packet processor meets Metro Ethernet demands
The Wintegra PWE3 solution now meets the G.823 and G.824 jitter and wander masks in traffic conditions as defined by the Metro Ethernet Forum and G.8261-draft.
Wintegra has added adaptive clock recovery to its suite of multi-service access support. This proprietary algorithm enables the Wintegra PWE3 solution to meet the G.823 and G.824 jitter and wander masks in traffic conditions as defined by the Metro Ethernet Forum and G.8261-draft. It also meets the more stringent requirements of 3G applications.
This opens new opportunities for using WinPath family products in wireless backhaul applications such as transport of T1/E1 (which connect Node B/BTS to RNC/BSC) over Metro Ethernet and 2G/3G collocation.
Wintegra offers a multiservice access solution that supports termination of multiple protocols - including ATM UNI, IMA, PPP, ML-PPP, FR, MFR, CES and PWE3 (TDM, ATM, HDLC) - which can be used at the same time, over different T1/E1 interfaces.
Two solution densities are available, up to 16 T1/E1 (512 DS0s channels) using only external framers, and up to 336 T1/252 E1 (8064 DS0 channels) using an external FPGA (for which Wintegra provides the IP core) and a framer/mapper.
Once the protocols are terminated, the data can be interworked to a cell or packet back-plane or uplink, either by using switching, bridging or MPLS routing.
One of the newest protocols supported in the framework of this solution is PWE3 (pseudo wire emulation edge-to-edge), that allows for the transport of different formats of data over packet networks.
When transporting TDM data over a packet network (in most cases using draft-ietf-pwe3-satop or draft-ietf-pwe3-cesopsn), the TDM timing information is lost.
If there are no external means for synchronisation, the TDM clock needs to be recovered from the arrival rate of the packets that transport the TDM data.
This is a particularly challenging operation, considering the low jitter/wander requirements of T1/E1 clocks and the typical behaviour of packet networks that includes large packet delay variations, lost packets and re-ordered packets.
The Wintegra adaptive clock recovery solution meets this challenge using a proprietary algorithm that runs on its packet processor in datapath software.
This solution meets the stringent requirements of G.823 and G.824 jitter and wander masks.
The measurements were performed for network conditions defined by the Metro Ethernet Forum documents and also according to the ITU-T Recommendation G.8261 ('Timing and synchronisation aspects in packet networks').
This recommendation defines the maximum network limits of jitter and wander and the minimum equipment tolerance to jitter and wander that needs to be provided at the boundary of packet networks at TDM interfaces.
For a test report, contact Wintegra.
The solution also meets the more restrictive requirements of TS-25.402 (Testing Synchronisation in UMTS networks) which makes it well suited for 3G (and 2G) wireless applications.

RS485 transceivers need no termination resistors
Half- and full-duplex RS485 transceivers feature switchable integrated termination.
Linear Technology has introduced the LTC2859 and LTC2861, half-duplex and full-duplex RS485 transceivers with switchable, integrated termination. Traditional RS485 networks require 120ohm termination resistors to be installed by the end user based on the physical layout of the twisted-pair wires and the placement of the nodes. As the bus is extended, the termination must be changed again by the end user.
Switching the integrated termination in the LTC2859/LTC2861 on or off under software control allows the proper nodes to be terminated without the end user's physical intervention.
In addition to the innovative termination capacity, the LTC2859/LTC2861 offer advanced transceiver features for industrial, medical and automotive applications.
A slew rate control pin allows datarates up to 20Mbit/s or a low-EMI mode at 250Kbit/s.
The bus pin protection exceeds +/-15kV for ESD strikes (human body model).
The receiver input impedance allows up to 256 nodes on a single bus.
These features provide more functionality than existing RS485 transceivers and the integrated termination combined with the tiny DFN package provide a smaller solution overall.
Specified over the commercial and industrial temperature ranges, the LTC2859 is offered in the 10-lead (3 x 3mm) DFN package and the LTC2861 is offered in the 12-lead (4 x 3mm) DFN and 16-lead SSOP packages.
Pricing begins at $1.55 each in 1000-piece quantities.
