General Description

The DS34S132 evaluation kit (EV kit) is an easy-to-use EV kit for evaluating the DS34S132 32-port TDM-overpacket (TDMoP) IC. The EV kit is a stand-alone system with a TDMoP chip, local oscillator, local control processor, 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 performance 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.

1. Introduction

1.1 Overview

The DS34S132 evaluation kit (EV kit) is a complete evaluation platform. The system consists of the following:

• Four octal E1/T1 transceivers (a transceiver is a

framer plus an LIU)

• TDMoPICdaughtercard

• MotorolaMPC8313CPUdaughtercard

• Peripheralmemoryandgluelogic

• RS-232 interfaceforcontrolandconfigurationusing

an ASCII terminal

1.2 Features

Three operating modes for E1/T1 are supported: unframed, framed, and framed-with-CAS. Bundles consisting of carrying entire TDM data streams or selected TDM time slots are transported over the network based on IP/MPLS/MEF addressing.

VLAN tagging and priority labeling are supported, according to 802.1p and Q. The type of service (ToS) of outgoing IP packets is user-configurable.

Synchronization between TDM interfaces is maintained by deploying advanced clock distribution mechanisms. The clocking options include internal, loopback, recovered clock (either adaptive or common clock), or an externally provided E1/T1 station clock.

The TDMoP IC is connected to 32 E1/T1 transceivers (four DS26518s) on the motherboard to complete the TDM-to-packet path.

DS34S132 Evaluation Kit Evaluates: DS34S132

Ethernet Uplink. The Ethernet uplink interface complies with the following standards: IEEE 802.3, 802.3u, and 802.1p and Q. This interface is a standard 100/1000BASE-T full-duplex Ethernet port with autonegotiation support. The EV kit supports VLAN tagging and priority. A different VLAN can be configured for each bundle. The data stream coming from the E1/T1 interfaces is encapsulated into IP/MPLS/MEF packets and transferred over the Ethernet port, and vice versa. When using IP, a destination IP address should be configured for each bundle. When using MPLS, a bundle should be configured with an MPLS label.

Ethernet Management. The local Ethernet management interface enables the connection of a software debugger to the DS34S132 EV kit CPU. The interface is a standard

1.5.2 Modes of Operation

The EV kit modes of operation for E1/T1 are the following:

• Unframed

• Framed

• Framed-with-CAS

In unframed mode, the entire incoming bit stream from each interface is encapsulated into IP/MPLS/MEF-over-

REF-CLK

REFERENCE CLOCK

RS-232 CONTROL

ETH-UPLINK

ETHERNET MANAGEMENT

Ethernet packets without regard for frame alignment. This option provides clear channel end-to-end service.

In framed and framed-with-CAS modes, the incoming bit stream is regarded as a sequence of n x 64kbps channel groups. This mode allows fractional or full E1/ T1 transmission.

1.5.3 Timing Modes

The E1/T1 transmit (Tx) clock operates in several timing modes to provide maximum flexibility for the EV kit TDM interface. The available timing modes are the following:

• Loopback Timing: The clock is derived from the received TDM clock.

• Recovered Clock Timing: The clock is regener- ated from the ETH network using the clock recovery mechanism.

• Internal Clock Timing: The clock is provided by an internal oscillator.

• E1/T1 Station Clock Timing: The clock is provided by the external E1/T1 clock source.

These selections are accessed through the user interface software. See 4.3 Configuring TDM Interfaces for more information. Figure 1-5 shows the TDM backplane wiring for one E1/T1 port of the system (there are 32 total E1/T1 TDM ports).

1.5.4 Ethernet Clock Recovery

The DS34S132 uses either CMNCLK or REFCLK pins as its reference clock input to recover the TDM timing from the Ethernet source using either “Adaptive Clock Recovery” or “Differential Clock Recovery.” These clock inputs are sourced from the on-board CPLD and are user-selectable from TCXOs, an OCXO, an E1/T1 station clock, or an external reference on one of the BNC jacks (CMNCLK or REFCLK BNC jacks).

1.5.5 Motherboard

The motherboard consists of four octal T1/E1 transceivers, a timing synthesizer (DS3100 clock sync), various TCXOs, an OCXO, two CPLDs, and an FPGA.

The DS3100 clock sync provides clock sources to the CPLD, which acts as a mux to allow software selection of the various clock sources to the DS34S132.

The FPGA provides CPU timing signals to the devices on the address/data bus. One CPLD provides userselectable clock sources and the other CPLD breaks out ports 31 and 32 of the TDM backplane for connection to an alternative LIU (e.g., the T3/E3 LIU, DS3150).

1.5.6 CPU Board

Figure 1-6 shows the CPU and peripherals block dia-

gram. The CPU clock is obtained from an on-board local crystal oscillator.

The flash device has a 64Mb memory capacity. The flash is used for storage of software and configuration data that should not be lost when system power is off. The RAM memory consists of a DDR2 SDRAM device with a capacity of 512Mb. The CPU provides 16-bit data bus synchronous with the address bus. The CPU can accept and prioritize multiple external interrupts. One interrupt is connected to the TDMoP IC daughter card. MPC8313’s SMC communication port, used as a UART, is connected through an RS-232 transceiver to the DB9 control port on the front panel of the system. An ASCII terminal connected to the control port can be used to configure the system. The MPC8313’s Ethernet communication controller is connected through an Ethernet PHY to the Ethernet management port (MNG) on the front panel of the system.

1.5.7 TDMoP IC Daughter Card

The TDMoP IC daughter card is populated with a Maxim TDMoP IC (DS34S132) and a 512Mb DDR SDRAM. The core voltage is 1.8V for the TDMoP IC. I/Os are supplied with 3.3V. In addition, 2.5V is made from the 3.3V power supply through an on-board linear regulator.

1.5.8 Bundles

A bundle is defined as a stream of bits originating from one TDM interface that are transmitted from a TDMoP source device to a TDMoP destination device. For example, a bundle can comprise any number of 64kbps time slots originating from a single E1 or T1 interface. Bundles are single-direction streams, frequently coupled with bundles in the opposite direction to enable fullduplex communications. More than one bundle can be

transmitted between two TDMoP edge devices. Each bundle transmitted or received by the EV kit uses one of the following payload type methods:

• TDMoIP using CESoPSN or SAToP payload type

method

• TDMoMPLSusingCESoPSN orSAToPpayload type

method

• TDMoMEF using CESoPSN or SAToP payload type

• HDLCoIP

• HDLCoMPLS

Up to 256 bundles are supported. Each TDMoP bundle/ connection can be assigned to one of the payload type machines or to the CPU.

1.5.10 TDMoP Mappings

To transport TDM data through packet switched networks, the EV kit encapsulates it into Ethernet packets, as shown in Figure 1-10. The UDP/IP, L2TPv3/IP, MEF, and MPLS headers, as well as the TDMoIP control word, are detailed in the packets formats section of Maxim's TDMoP IC data sheets.

1.5.11 Payload Type Machines

SAToP. The SAToP payload type machine converts

unframed E1/T1 or serial data flows into IP, MPLS, or Ethernet packets and vice versa according to ITU-T Y.1413, MEF 8, MFA 8.0.0, and IETF RFC 4553.

of time slots inside a bundle according to ITU-T Y.1413, MEF 8, MFA 8.0.0, and IETF RFC 5086.

HDLC. The HDLC payload type machine, for efficient transfer or termination of frame-based traffic, provides an HDLC controller for each bundle assigned to it. It supports 2, 7, and 8-bit time-slot resolution (i.e., 16, 56, and 64kbps, respectively), as well as N x 64kbps bundles (N = 1 to 32). This is useful in applications where HDLCbased signaling interpretation is required (such as ISDN D-channel signaling termination, V.51/2, or GR-303), or for trunking packet-based applications (such as frame relay), according to IETF RFC 4618.

assigned with OAM, TDMoIP traffic is not sent immediately. 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 transmitting 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 sections 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 parameter. 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IC’simmunitytonetwork

packet delay variation.

• Thedataarrivingfromthenetworkisdelayedbydifferential 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.

3.2 User Interface Software

3.2.1 Using the Control Port and an ASCII Terminal

The EV kit can be configured and monitored using an ASCII terminal connected to the control port on the EV kit front panel. The control port is a V.24/RS-232 asynchronous DCE port terminated in a 9-pin, D-type female connector. The EV kit continuously monitors control port signals from the ASCII terminal and immediately responds to any input string received through this port.

To access the user interface software using an ASCII terminal:

1) Ensure all DS34S132 EV kit cables and connectors are properly connected.

2) Connect the DS34S132 EV kit to a PC equipped with ASCII terminal emulation software (for example, Windows Hyper Terminal or PuTTY).

3) Set the port parameters of the control terminal PC to

115.2kbps, 8 bits/character, 1 stop bit, no parity. If available, set the terminal emulator to ANSI VT100 emulation (for optimal view of system menus).

4) At the end of the initialization and self-test, system software detects the part number of the TDMoP IC on the internal daughter card and displays it on the terminal screen as:

The login ID is target and the password is password.

After giving the password, the screen shows:

3.2.2 Using Telnet Through the Ethernet Management Port

The EV kit can be configured and monitored remotely over an IP/Ethernet network. Currently, the DS34S132 only supports static IP (factory default is 10.16.34.18) so the user needs to program the correct IP address. Use the following steps to do this. Remember that the user only needs to do this once.

To configure the static IP address of the DS34S132 EV board:

1) Power the DS34S132 EV kit.

2) Connect the MNG port of the EV kit to the local IP/ Ethernet network.

3) Use an ASCII terminal connected as previously described.

The login ID is root and the password is also root.

After giving the password, the screen shows:

~ #

Write the following commands in sequence as shown

below:

~ # cd /etc/rc.d

/etc/rc.d # vi rc.conf

The user then needs to change the necessary param-

eters for ‘eth0’ (lines between ‘net interface 0’ and ‘net interface 1’). Once complete, save and exit.

/etc/rc.d # reboot

To access the user interface software using a telnet session:

1) Power the DS32S132 EV kit.

2) Connect the MNG port of the DS34S132 EV kit to the local IP/Ethernet network.

3) IP address was decided above.

4) On a PC is connected to the IP/Ethernet network, run “cmd” to get a DOS-like text interface window.

5) At the command prompt, type telnet followed by the IP address determined in step 3.

6) At the login prompt, type target. At the password prompt, type password.

Write the following commands in sequence as shown

below:

~ $ su

~ $ password: root

~ $ ./ins132

~ $ ./top32App

The Main Configuration (S132) menu is displayed in

the terminal.

top32App can be executed again after exiting the

To redisplay the current menu, type r and press Enter or simply press Enter.

3.2.5 Saving Changes

After changing the values of one or more parameters in a configuration menu, type s then Enter to save the changes and write them to the TDMoP IC. If changes are

not saved in each menu, attempts to change parameters in other menus may not behave as expected.

For example, changes in the Interface Configuration menu must be saved before activities in the Bundle Configuration menu behave correctly, especially when saving a bundle configuration.

OAM ID n [0 - 0xFFFF]

Enables/disables OAM ID n (2 P n P 8).

Specifies OAM ID n (2 P n P 8). These IDs are bundle IDs for UDP/ IP-specific OAM. If the bundle ID of an incoming packet matches an enabled OAM ID, the packet classifier in the TDMoP IC considers the packet to be an OAM packet and discards or forwards it to the CPU as specified by the OAM packet field described above.

4.3 Configuring TDM Interfaces

The number of TDM interfaces available depends on the TDMoP IC on the daughter card. A DS34S132 has 32 TDM interfaces. The user interface software only allows configuration of the number of TDM interfaces actually supported by the installed IC.

To configure a TDM interface, select Interface Configuration from the Main Configuration (S132) menu and enter the interface number at the prompt (Figure 4-4). The Interface Configuration menu is then displayed, either Figure 4-5 (E1) or Figure 4-6 (T1), depending on the setting of the Link Type parameter in the PreConfig Configuration menu.

Connect: Link is connected. Disconnect: Link is disconnected.

Default: Connect

CSU: If the port interface operates as a CSU, it is necessary to adjust the T1 output transmit level for reliable operation of the network and for compliance with FCC Rules Part 68A. This adjustment is used to minimize the interference caused by a local transmit signal to other users that transmit their signals on other pairs of the same cable. The required setting depends mainly on the length of the cable that connects between the T1 port and the first repeater down the link. Repeaters are usually located every mile, and, therefore, they are designed to optimally handle signals attenuated by one-mile length of cable. If the T1 port is closer, the repeater receives a T1 signal at a higher level. This does not significantly improve handling of the T1 signal, but certainly increases the interference coupled from the T1 pair to repeaters that serve other pairs in the cable. To prevent this, an attenuation value can be selected that brings the T1 signal level closer to the expected repeater signal level. This is achieved by enabling circuitry in the T1 transmitter that preattenuates the signal by 7.5dB, 15dB, or 22.5dB, effectively emulating 1000ft, 2000ft, or 3000ft of cable.

DSU: In this case, the transmit signal mask can be selected in accordance with the transmit line length, to meet DSX-1 requirements, as specified by AT&T CB-119, or operation in accordance with FCC Rules Part 68. For compliance with DSX-1 specifications per AT&T CB-119 and ANSI T1.102-1987, select the value corresponding to the length of the cable (in feet) connected between the T1 port connector and network entry point.

Counter of successfully transmitted packets for which transmission is inhibited by 2 to 15 collisions. Recommendation: Use a full-duplex mode if possible.

The number of packets experiencing deferral due to carrier sense being active on the first attempt at transmission. Packets involved in any collision are not counted nor are packets that experienced a transmit underrun.

The number of packets that were not transmitted due to transmit FIFO underrun.

To allow collision detection to work properly, the period in which collisions are detected is restricted (512 bit-times). For 10BASE-T Ethernet (10Mbps), it is 51.2Fs; for Fast Ethernet (100Mbps) it is 5.12Fs. For Ethernet stations, collisions can be detected up to 51.2 Fs after the beginning of the transmission, or in other words, up to the 512th bit of the frame. When a station detects a collision after it has sent the 512th bit of its frame, this is counted as a late collision. Note: A late collision is counted twice—as a collision and

as a late collision.

Recommendation: Check if there is incorrect cabling or a non-compliant number of hubs in the network. Bad network interface cards (NICs) can also cause late collisions.

The number of packets successfully transmitted for the bundle. When a valid connection is established, the number increases steadily.

The number of packets successfully received for a bundle. When a valid connection is established, the number increases steadily.

There are two possible reasons for lost frames: Packet or packets are dropped or lost somewhere along the network. Reordering of packets by network. Packet reordering can occur due to queuing mechanisms, rerouting by the network, or when the router updates very large routing tables and is therefore overloaded.

Recommendations:

Ensure the EV kit traffic has sufficient bandwidth. Ensure the Ethernet connection is functioning properly. Ensure the Ethernet/IP network provides priority (quality of service) to the EV kit traffic. Priority can be achieved by two means: VLAN tagging and IP ToS marking. Verify that the IP network devices (switches/routers/modems/etc.) can handle the EV kit PPS (packets per second) rate. Ensure the network devices do not drop/lose/ignore packets by checking their statistics.

PARAMETER DESCRIPTION

Maximum JB Level [Usec] The maximum jitter buffer level for the current bundle. Discarded Packets in Rx Number of received packets that were discarded by SAToP/CESoPSN payload type machine.

Reordered Packets in Rx

Underrun Occurred

Number of received misordered packets that were successfully reordered by SAToP/ CESoPSN payload type machine.

An underrun situation can be caused by: Buffer starvation: Packets delay variation causes the buffer to empty out gradually until it underflows. Continuous sequence errors: The sequence error means a halt in the valid stream of packet arrival into the jitter buffer. Packets are stopped/lost/dropped. Differential timing (PDVT) configuration that is not large enough to compensate for the network delay variation. In a TDM network, all system elements must be locked to one master clock. If not, it leads to a situation in which data is clocked out of the jitter buffer at a rate different from the one that is clocked in. This gradually results in either an overflow or underflow event, depending on which rate is higher. The event repeats itself periodically as long as the system clock is not locked. Recommendations: Try increasing the differential timing (PDVT) in a bundle configuration. Check reasons for sequence errors or lost/dropped packets (if present), system clocking configuration, Ethernet environment (full duplex), and connection, packets drop/loss/ignore by routers/switches or nonuniform packets output by routers/switches due to queuing mechanisms. Ensure the same number of time slots for bundle is configured on each end. Ensure the Ethernet/IP network provides priority (quality of service) to the TDMoP traffic. Priority can be achieved by two means: VLAN tagging and IP TOS marking.
