IES-1248-51V User’s Guide

Profile Select a profile of ADSL settings (such as the transfer rate, interleave

delay and signal to noise ratio settings) to assign to this port. Use the

Port Profile screen to configure port profiles (see Chapter 17 on

page 139).

Mode Select the port’s ADSL operational mode. Select the mode that the

subscriber’s device uses or auto to have the IES-1248-51V

automatically determine the mode to use. See Table 19 on page 119

for information on the individual ADSL modes.

Alarm Profile Select the port’s alarm profile. The alarm profile defines alarm

thresholds for the ADSL port. The IES-1248-51V sends an alarm trap

and generates a syslog entry when the thresholds of the alarm profile

are exceeded (see Section 17.6 on page 148).

IGMP Filter Profile The IGMP filter profile defines which multicast groups a port can join.

Select a profile of IGMP filter settings to assign to this port. Use the

IGMP Filter Profile screen to configure IGMP filter profiles (see

Section 20.7 on page 180).

ADSL2/2+

feature

These are features available with ADSL2/2+. The subscriber’s ADSL

device must also support the individual features in order to use them.

At the time of writing these features have not been fully tested and

their performance and interoperability cannot be guaranteed.

Annex L Enable Annex L to use reach extended ADSL2. This allows increased

connection distances.

Annex M Enable Annex M to use double upstream mode. This has the upstream

connection use tones 6 to 63.

Annex I Enable Annex I to use all digital mode. With Annex I, the ADSL

connection uses the full spectrum of the physical line and the user can

not use POTS or ISDN service. This increases the upstream data rate.

Note: The subscriber cannot use POTS or ISDN services when

you enable Annex I.

PMM Enable the Power ManageMent (PMM) feature to reduce the amount of

power used overall and reduce the instances of the connection going

down. PMM increases or decreases the transmission power based on

line conditions. PMM also decreases the number of service

interruptions.

Select L2 to have the ADSL connection use power saving mode and

reduce the rate when there is no traffic. The rate comes back up when

there is traffic.

Select L3 to use both power management modes L2 and L3. L3 puts

the ADSL connection to sleep mode.

L0 power mode uses no power reduction. See the ITU-T G.992.3

standard for more on PMM and the power modes (states).

SRA Enable Seamless Rate Adaptation (SRA) to have the IES-1248-51V

automatically adjust the connection’s data rate according to line

conditions without interrupting service.
