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:

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 periodeither 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 TCA profile types and parameters

System statistics generated on the Speed Touch 591s can be used to monitor two types of congestionframe 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.

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 ersthe 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.
