evaluates: ds34s132 ds34s132 evaluation kit general description the ds34s132 evaluation kit (ev kit) is an easy-to-use ev kit for evaluating the ds34s132 32-port tdm-over- packet (tdmop) ic. the ev kit is a stand-alone system with a tdmop chip, local oscillator, local control proces - sor, memory, external e1/t1 lius and framers, power supply, and user interface software included in a 2.5 ru enclosure. the ev kit is controlled over an rs-232 serial link from an external ascii terminal (typically using terminal emulation software running on a pc) or through a telnet session. the ascii user interface is menu driven and hierarchical for easy use. the behavior and perfor - mance of the tdmop ic can be evaluated with a single ev kit where the ethernet signal is looped back to the kit, or with two ev kits configured as separate end points. ev kit contents ds34s132 ev kit system tdmop ic daughter card (factory installed) mpc8313 cpu daughter card (factory installed) user interface software (factory installed) ordering information features s complete system: motherboard and daughter cards in a convenient 2.5 ru enclosure s menu-driven ascii text user interface software s system processor on a separate daughter card s ethernet phys, i/o jacks, e1/t1 transceivers, and clock sources on motherboard s built-in ac power-supply module s several popular tcxo and ocxo oscillators from which to select and bnc connectors for lab references s 9-pin serial jack to connect an ascii terminal for configuration and status s system tcp/ip stack for configuration and status over ip/ethernet s one rj45 ethernet jack for connection to the ethernet network s one rj45 jack for each e1/t1 port s rj45 external clock input jack s bnc common clock input jack s bnc reference clock input jack s 16-bit cpu interface to tdmop ic tdmoip ? evaluation system with no lid 19-5865; rev 0; 5/11 tdmoip is a registered trademark of rad data communications, ltd. part type DS34S132DK ev kit for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim?s website at www.maximintegrated.com. downloaded from: http:///

15 maxim integrated evaluates: ds34s132 ds34s132 evaluation kit assigned with oam, tdmoip traffic is not sent immedi - ately. first, a tdmoip echo request packet is sent once every five seconds. this continues until a valid echo reply arrives. the remote tdmop system receives the echo request packet and sends a valid echo reply only if all parameters in the echo request match its local configuration. when a valid echo reply arrives, the trans - mitting echo request message stops, and tdmop traffic flow begins at full rate for that bundle. if there is a break in the connection, the initialization process begins again. refer to the vccv oam and udp/ip-specific oam sec - tions of the ds34s132 ic data sheet for details of the oam payload types. 1.5.13 packet delay variation packets are transmitted at set intervals. packet delay variation (pdv) is the maximum deviation from the nominal time the packets are expected to arrive at the receiving device. the tdmop ic controls a buffer that compensates for the deviation from the expected packet arrival time to prevent buffer overflow or underflow. packet delay variation is an important network parame - ter. large pdv (exceeding the jitter buffer configuration) causes receive buffer overflow or underflow and errors in the recovered e1/t1 signal. to compensate for large pdv, the packet delay variation tolerance (pdvt) (jitter) buffer should be configured to a higher value. 1.5.13.1 differential time the tdmop ic is equipped with a pdvt buffer. the pdvt buffer is filled by the payload of incoming packets and emptied to fill the outgoing e1/t1 or serial data stream. the jitter buffer depth is defined by the rx_max_buff_size parameter. when the jitter buffer level reaches the value of rx_max_buff_size, an overrun situation is declared. the differential time parameter defines the amount of data to be stored in the jitter buffer to compensate for network delay variation. this parameter has two implications: ? differential time defines the ics immunity to network packet delay variation. ? the data arriving from the network is delayed by dif - ferential time before it is sent to the tdm interface. differential time should be smaller than rx_max_buff_ size. also, the difference between rx_max_buff_size and differential time should be larger than the time required to reconstruct a packet (otherwise an overrun can occur). configuring the jitter buffer parameters correctly avoids underrun and overrun situations. underrun occurs when the jitter buffer becomes empty (data is being written to the buffer more slowly than data is being read out of the buffer). overrun occurs when the jitter buffer is full and there is no room for new data (data is being read out of the buffer more slowly than data is being written to the buffer). see figure 1-12 . table 1-1 shows the maximum configurable value for differential time. figure 1-11. packet delay variation table 1-1. maximum pdvt for e1/t1 pdv tt packets leaving the near-end of the evaluation board packets arriving at the far-end of the evaluation board tdm frame type e1 (ms) t1 (ms) unframed 256 340 framed-without-cas 256 256 framed-with-cas 256 192 downloaded from: http:///
