1.1 About SHDSL

DSL technology dramatically increases the digital capacity of ordinary telephone
lines (the local co pper loo ps). The sp eeds obt ainabl e using DSL te chn ology ar e tied
to the distance between the customer and the Telco central office. The SHDSL
variant of DSL technology is designed for business applications, where high speed
is required in both transmission dire ctions. SHDSL is a rate-adaptive techn ology,
which, unlike ADSL, cannot share lines with analog telephones.

SHDSL provides symmetric DSL d elivery over a single coppe r pair at rat es between
192 kb/s and 2304 kb/s, and a 35% to 50% improvement in distance at a given rate
over traditional symmetric DSL. It is a purely digital technique that uses the lower
band of frequencies to achieve range performance while maintaining the ability to
transmit voice or data services symmetrically.

The narrower frequency band of SHDSL reduces the possibility of interference or
crosstalk when it is d epl oye d in the same binder group or cable as other DSL-based
services, such as ADSL.

Performance varies with loop cha ract eristic s, such as len gth, wire gau ge, noise, and
the number and location of bridged taps and gauge changes. Best performance is
obtained on short, clea n loops. The SHDSL bit rate can be configured to adapt to the
line conditions.

1.2 Overview of the Speed Touch 591s

The Speed Touch 591s is a device that provides SHDSL access to the ATM core
network from customer pre mises. It can be manage d locally usi ng its own NMTI via
its serial port, or remotely using the 5620 Network Manager. Four versions of the
Speed Touch 591s are available:

• frame r elay

• V.35/X.21 circuit emulation

• T1 circuit emulation

• E1 circuit emulation

Figure 1-1 shows the front view of the Speed Touch 591s, which is the same for all
versions. Figure 1-2 shows the back view of the frame relay and V.35/X.21 circuit
emulation version, and Figures 1-3 and 1-4 show the back views of the T1 and E1

4 — Configuring generic node parameters

Configuring the serial port baud rate

The Speed Touch 591s provides a serial port for connection to serial
transmission-based node management terminals. Initially, the baud rate of the node
management terminal must be set to match the Speed Touch 591s default value of

9.6 kb/s to establ ish communication. Aft er the terminal establi shes connection, a new
baud rate can be configured for the serial port.

If the serial port baud rate is changed, the change takes effect when PROCEED is
selected. Change the baud rate of the node management terminal to match the new
baud rate of the serial port.

Procedure 4-1 Configuring the baud rate

HOUSE — SER_PORT_1 — BAUD_RATE — 600 or 1200 or 2400 or 4800 or 9600* or 19200

Configuring the DSLAM type

The Speed Touch 591s can be configured to be compatible with either of two types
of DSLAM—DSLAMs that support CPSS or DSLAMs that do not support CPSS.

If the Speed Touch 591s i s con nected to a 7350 ASAM, con figur e the DSLAM type
as 7350. If the Speed Touch 591s is connected to a 7300 ASAM or any other
DSLAM, configure the DSLAM type as 7300.

Note — Configuration of this parameter does not affect SHDSL

interoperability—it only specifies how the Speed Touch 591s
communicates with the DSLAM for management purposes.

Procedure 4-5 Configuring the DSLAM typ e

HOUSE — MORE — DSLAM_TYPE — 7350* or 7300

Configuring the control IP address

The control IP address is the IP address of the Speed Touch 591s. It can be
configured manually when the Speed Touch 591s is operating with a 7300 ASAM.

Note — The new IP address is not applied until the destination IP

address, subnet mask, and control VP/VC have been correctly
configured individually, and the configuration has been applied
globally—see procedure 4-10.

Procedure 4-6 Configuring the control IP address

HOUSE — MORE — IP_ADDRESSES — CTLIP — <ipaddress> ↵

Configuring the destination IP address

The destination IP address is the IP address of the remote host.

Note — The new IP address is not applied until the control IP

address, subnet mask, and control VP/VC have been correctly
configured individually, and the configuration has been applied
globally—see procedure 4-10.

Procedure 4-7 Configuring the destination IP address

HOUSE — MORE — IP_ADDRESSES — DESTIP — <ipaddress> ↵

where ipaddress is the IP address of the gateway in the decimal format #.#.#.# and where
# is in the range 0 to 255

Configuring the subnet mask

The subnet mask for the domain containing the Speed Touch 591s must be
configured manually when the Speed Touch 591s is operating with a 7300 ASAM.

Note — The new mask is not applied until the control IP address,

destination IP address, and control VP/VC have been correctly
configured individually, and the configuration has been applied
globally—see procedure 4-10.

Procedure 4-8 Configuring the subnet mask

HOUSE — MORE — IP_ADDRESSES — SUBNET_MASK — <mask> ↵

4 — Configuring generic node parameters

4.2 Configuring the network port

Since the Speed Touch 591s is a slave to the CO device at the other end of the
SHDSL line, the majority of network port parameters are configured by the CO
device.

The CO device can configure, enable, or disable the following parameters on the
network port on the Speed Touch 591s:

• SHDSL line rate (192, 384, 512, 768, 1024, 1152, 1536, 2048, or 2304 kb/s)

• signal-to-noise margin threshold

• power backoff

• loopbacks

• PSD mask used on the SHDSL line (Europ ean or North Ame rican, s ymmetric or

asymmetric)

The only network por t par ameter that can be confi gured lo cally on the Speed Touch
591s NMTI is power backoff.

Power backoff

The power backoff feature automatically reduces the power transmitted by the
network port over the SHDSL line. During the line training phase, the transmitted
power is compared with the strengt h of the signal received at the other end of the line.
If possible , transmit power is then reduced to a level that is sufficient for th e signal
to be correctly rec eived at the other end of th e line while still mainta ining a maximum
BER of 10

-7

.

On short or relatively loss-free lines, this feature reduces the risk of crosstalk being
generated on neighb ori ng l in es b y unne ces sa rily strong signals whe n a l ower si gna l
strength would still produce a clean signal at the receiver.

Note — Power backoff configurations contained in EOC requests

from CO devices at the other end of the SHDSL line override any
local NMTI power backoff c onfigurations on the Sp eed Touch 591s.

Pacing

The Speed Touch 591s uses pacing to control t he rate at wh ich frame relay and frame
forwarding traffi c travel s from the user por t to the networ k port. Pac ing smooths out
traffic peaks so that the data is transmitted more evenly, thus avoiding peaks at the
receiving end, usually a central node. Since the central node receives data
simultaneously from s everal different sources, bursts of data can cause con gestion on
the node. Use of the pacing feature prevents this problem.

The SHDSL line on the Speed Touch 591s network port runs at a much faster rate
than the user port. Without pacing, frames arriving on the user port would be
converted to ATM cells and sent out at the SHDSL line rate on the network port,
producing bursts of data at the receiving end. Pacing allows the data frames to be
more evenly spread in cells on the SHDSL line, with empty cells inserted between
data cells. Th is helps with traff ic management on the r eceiving e nd because the node
can discard the empty cells, giving it more time to process the data cells.

Default pacing values are calculated and applied by the Speed Touch 591s as a
function of the user port clock rate (see section 5.1 for details) and the SHDSL line
rate. The device on the other end of the SHDSL line dic ta tes the li ne rate across the
SHDSL line because the Speed Touch 591s acts as a slave device.

7 — TCA profiles

7.1 Overview

TCA profiles are used for system surveillance and allow such parameters as the
quality of a line or the degree of system congestion to be monitored. A TCA pr ofi le
reads system statistics over a user-defined period—either every 15 min or every
24 h. It then d etermi nes whe ther any stat isti cs co unter has e xce eded i ts us er-de fined
threshold over a sufficient period of time on the user port on the Speed Touch 591s
to justify generating an alarm.

TCA profiles combine several statistics in a single profile; therefore, the user does
not have to constantly monitor individual statistics to determine if the system is
operating as anticipated.

TCA profiles are created and applied in three stages:
1 creation of the TCA profile (configuration of statistics thresholds, name of the

TCA profile, etc.)

Note — If a specific threshold for a performance parameter is not

preset in the TCA profile, the parameter takes its default value and is
still monitored by the profile.

2 assignment of the profile to one or more ports
3 enabling of the profile on the port or ports

The following sections give details on how to configure TCA profiles.

Note — Although not mandat ory, it is recomme nded that configured

TCA profiles always be named to help identify them.

7-2 Speed Touch 591s Technical Practices

90-8785-01 February 2001

7.2 TCA profile types and parameters

System statistics generated on the Speed Touch 591s can be used to monitor two
types of congestion—frame relay card congestion and frame relay stream
congestion. Two corresponding types of TCA profiles are available:

• FRCC

• FRSC

On the Speed Touch 591s, FRCC co ngestion corresponds t o congestion on the Spee d
Touch 591s itself, and FRSC corresponds to congestion on the user port.

When a TCA profile is configur ed fo r t he Spe ed Touch 591s, you must first choose
the type of congestion for which to define thresholds and profiles. Procedures for
defining a Speed Touch 591s TCA profile differ slightly depending on whether
FRCC or FRSC is chosen. However, both types of congest ion are de termined b y the
same frame relay thresholds —ACT, SCT, and MCT. Refer to Alc at el 7350 ASAM
Technical Practices for further information on these thresholds.

TCA profiles for the Speed Touch 591s are based on two parameters:

• the maximum permissible time, in seconds, that frame relay thresholds can be

exceeded before an alarm is generated

• the frame relay thresholds ACT, SCT, and MCT expressed as a percentage of

resources used

7 — TCA profiles

These two parameters interact. The system reads the values of the three frame relay
congestion threshol ds every second and compa res th em wit h t he configured values.
If it finds that a thres hold has exceeded t he configured val ue, it increments a counter
to indicate that this frame relay thre shold has been ex ceeded for that secon d, the next
second, and so on.

Meanwhile, the syste m c ompar es the value of this counter wi t h th e t h re sho ld t hat is
set for the maximum permissible time, and if the threshold has been exceeded for
longer than this time, an alarm is generated. The profile manages a two-tier threshold
system to detect frame relay congestion on the Speed Touch 591s system resources
or the line.

The V.35/X.21 circuit emulat ion version of the Speed Touch 591s supp orts two data

mode (AAL1).

Procedure 8-8 Configuring the AAL service type

Table 8-2 Circuit parameters

CONFIG — OBJECT — PORT — <U> ↵ — CIRCUIT — AAL_SERVICE — UDT or SDT_BASIC

Playout buffer size

The playout buffer for data flowing from the network port to the user port can be
configured to co mpensate for the e ffects of posit ive and negative cell delay vari ation.
Cell delay variation is a measurement of the difference in cell propagation delay
occurring on a connection. The playout buffer depth is set to absorb the negative
CDV characteristics of the network (the increased time between the arrival of
consecutive cells, or cell spacing) by ensuring that the buffer has sufficient data so
that the data stream does not run dry between cell arrivals.

Conversely, the pla yout buf fer mus t als o absor b the pos itiv e CDV chara cteri stic s of
the Speed Touch 591s and network (cells being received with a very short delay
between them, or cell clumping) by providing sufficient cell storage space in the
buffer to avoid overflow under clumping conditions. Buffered data is sent on the
V.35 serial stream at a constant rate, w hich is indep endent of the rate at which the
cells are r eceived.

The setting for CDVT de termines how m uch CDV can be tol erated befor e the Speed
Touch 591s is forced to insert erroneous (fixed-pattern) data. A high CDVT setting
allows the AAL1 VC to tolerate a hi ghe r CDV wi tho ut er rors, but at the expense of
a higher transfer delay through the Speed Touch 591s. The CDVT cannot be
configured and is set by default to half the playout buffer size.

CONFIG — OBJECT — PORT — <U> ↵ — CIRCUIT — PLAYOUT_BUF — <value> ↵

where value is a value between 1 and 12 ms, in increments of 0.5 ms

Partial cell filling

Partial cell filling minimizes cell assembly delay by only partially filling the cells
with user data and filling the remaining space with padding octets. This speeds up
cell assembly because the Speed Touch 591s doe s not have to wait f or an entire cell
of data to be received before sending the cell.

Partial cell fil ling is configur ed using two paramet ers—the number of da ta octets per
cell (which determin es how mu ch a ce ll is fil le d bef o re bein g sent) and the padding
octet pattern (which determines the format of the padding octets that are used to fill
the rest of the cell). If the fi rst parameter is conf igured as ALL, no padding octet s are
inserted into the cells.
