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.

1. Introduction
1.1 Overview
The DS34S132 evaluation kit (EV kit) is a complete evalu-
ation 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
• Clock subsystem based on the DS3100 clock sync
chip
• Uplinkportforthe100/1000MbpsEthernet(supports

ed to the MPC8313 Ethernet controller for debugging
• 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 con-
sisting 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, recov-
ered 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.

Evaluates: DS34S132
DS34S132 Evaluation Kit
Ethernet Uplink. The Ethernet uplink interface com-
plies 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 auto-
negotiation 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 inter-
faces 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
10/100/1000BASE-T Ethernet port with autonegotiation
support that complies with the IEEE 802.3 standard.
E1/T1 External Clock. The E1/T1 external clock port
enables connection of an external clock source to sup-
port the station clock mode.
Common Clock. The common clock port enables con-
nection of a common clock source through LVTTL input.
It supports frequencies of up to 25MHz. The common
clock is used for differential mode clock recovery.
Reference Clock. The reference clock port allows for an
external source to be used for TDM clock recovery from
the Ethernet link.
RS-232 Control. The RS-232 control interface enables
connection an ASCII terminal for configuring the EV kit.

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-
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 inter-
face 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 transceiv-
ers, 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 user-
selectable 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 com-
munication 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 full-
duplex 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 net-
works, 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.
CESoPSN. The CESoPSN payload type machine con-
verts structured E1/T1 data flows into IP, MPLS, or
Ethernet packets and vice versa with static assignment
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 sup-
ports 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 HDLC-
based 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.
1.5.12 OAM
OAM is used to detect a valid connection. It can be
set to enable or disable. When a bundle in the EV kit is

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IC’s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.

1.5.13.2 End-to-End Delay
The data path end-to-end delay, which is a function of
all connections and network parameters, is calculated
as follows:
End-to-End Delay = PDVT + Packet Creation Time +
Fixed Network Delay
where PDVT is measured in seconds, Packet Creation
Time is measured in seconds, and time of one time slot
= 1/8kHz.

where NF = number of TDM frames per packet.
1.5.14 End-to-End Alarm Generation
An end-to-end alarm generation mechanism exists in the
EV kit to facilitate the following alarms:
