Note that Unit O is configured to generate a transmit link clock of 128Kbps Int which is used internally as the GRX reference CLOCKING menu GRX source and also received by Unit 1 and used as the GRX reference CLOCKING menu GRX source Unit 1 then turns the clock around TX clock set to RXC and it is received back at Unit 0 which uses it as the RX clock source The programming of the clock references is essential to all tributary channels since they must use a clock reference to generate all local bit rates In this example the Global Receive clock bus GRX takes the Port 1 Aggregate RX clock and Port 2 which will be used to connect a router uses the GRX as its reference for generating the RX router clock To go one stage further and operate Port 2 dynamically the RX clock source is set to DBA This allows the V100 to smoothly vary the RX clock on Port 2 according to traffic demand Finally a destination address must be entered for Port 2 V100 Versatile Multiplexer Technical Manual Version 2 2 Page 190 of 231 CHAPTER 5 APPLICATION EXAMPLES 5 2 Use with Satellite Modems The V100 multiplexer is often used in combination with satellite modems to provide telecommunications links between remote sites This example describes the use of the V100 with a Paradise Datacom P300 modem that is fitted with the standard P1440 interface in RS422 mode thereby allowing the use of the standard RS422 RS449 cable part

4. Since bandwidth on the HSC is used for both control and data packets the maximum aggregate of all data routes via the HSC must not exceed 2Mbps in either direction so as to allow control packets to flow under all circumstances The HSC uses an RS485 style electrical interface and consists of RX and TX data pairs and separate RX and TX clocks All signals are bussed between units by a twisted pair cable and consist of one driving source and one receiver In the example below the master unit has an aggregate link to a remote unit and is linked via the HSC to the slave Data for a tributary port on the slave is received by the master routed to the slave and output from the relevant tributary channel AGGREGATE HSC MASTER GRE Source DATA 0 1 RxClock GT Source DATA 0 1 TxClock HSC SLAYE GRE Source HSC GTX Source HSC ag PLL TRIBUTARY y PLL 4 9 2 HSC Clocks The example above shows the simplest clock application where the aggregate RX clock drives the GRX of the master and is also looped back to the TX clock The GRX is then used as the reference to derive the 4Mbps HSC RX clock The HSC clock on the slave must be set to drive the GRX clock This GRX then becomes the reference for the tributary PLLs in the slave which derive the port clocks Each HSC clock bus must have only one driving source However either unit may be designa

A V100 network may be managed from the dedicated supervisor port of any chassis in the network The user logs on to the required unit and configures the network from the most convenient management port using a clear and simple display which may be accessed using a PC running a terminal emulation package such as HyperTerminal under Windows Alternatively the supervisor may be operated in a terse teletype mode for integration into a central network management system In either case the port uses an RS232 interface The supervisor may also be accessed using the telnet protocol in an IP network This user manual describes the use configuration and installation of the V100 multiplexer V100 Versatile Multiplexer Technical Manual Version 2 2 Page 9 of 231 CHAPTER 1 INTRODUCING THE V100 1 2 Capabilities 1 2 1 Analogue Voice FAX A wide range of ITU standard algorithms may be individually selected according to bandwidth and quality requirements with bit rates from 5 3Kbps up to 64Kbps All channels support Group 3 FAX at 2400 14400bps V 22 V 22bis and V 32bis modem relay and provide G 168 echo cancellation Bandwidth may be permanently assigned or used on demand to optimise link use when it may be redistributed among data channels using the Dynamic Bandwidth Allocation feature Comfort Tone Generation and input output gain adjustment allow the voice channels to be optimised for all situations The analogue voice cards are avai

9. In practice only 75 of this buffer is used for safety reasons before flow control is asserted at the port This means that at worst case the error correction can survive up to 9 seconds without receiving a good frame The principle used for error correction uses a NACK only protocol This means that a negative acknowledgement packet is sent back whenever a good frame is received out of sequence since at least one frame in the middle must be missing This NACK asks for the retransmission of frames starting with the first missing one Errors experienced on the link affect the whole 100mS superframe which has to be retransmitted When the error rate approaches 1 in 10e4 to 1 in 1065 the error correction will start to fail since every superframe will be received in error The technique therefore starts to reach a useful limit at error rates of around 1 in 10e5 When the channel input buffer reaches 7596 as caused by a poor link insufficient bandwidth or loss of carrier the CTS signal on the port is dropped by the multiplexer This signal must be connected to the DTE for the error correction to work Loss of carrier is then handled by asserting flow control to stop the input data Realistically this means that a channel should continue without data loss through carrier losses of up to at least 5 seconds PROVIDED it is configured so that it does not lose any data NOTE The Data Channel Flag parameter on the SYSTEM menu must be set to
