Whirlpool modem review Cisco 828 and SOHO 78 Routers Release Notes

This document describes new and changed information for the Cisco 828 and SOHO 78 Routers Software Configuration Guide.

PPPoE MTU CLI

When a Cisco 828 or SOHO 78 router terminates PPPoE traffic, a PC connected to the Ethernet interface may have problems accessing Web sites if the PC's maximum transmission unit (MTU) setting is too high. The MTU contains maximum segment size (MSS) values for the TCP packets transmitted by the PC. The default MTU setting is 1460.

To reduce the MSS value, enter the following command on the router Ethernet interface:

ip tcp adjust-mss mss

where mss is 1452 or less.

This command works only if NAT is configured on the router.

Configuration Example

The following example shows a configuration of a PPPoE client with the MSS value set to 1452.

vpdn-group 1

MMI and ILMI Availability

The Cisco 828 and SOHO 78 platforms do not support Modem Management Interface (MMI) and Integrated Local Management Interface (ILMI). The default for these features is off.

PPPoATM QOS Availability

Quality of service (QOS) is available for PPP over ATM when multilink PPP is configured. If mutilink PPP is not configured, the output queuing defaults to first-in-first-out (FIFO), and it cannot be changed.

Maximum Loop Length Configuration

Use this command if reaching maximum loop length is more desirable than maintaining line signal quality. When you use this command, the line signal quality may deteriorate, CRC errors may increase, and bit error rate (BER) may not meet the standard requirement. This command is mostly applicable when lower line rates are used.

Use the following command if you want to reach maximum loop length:

dsl snr threshold <15db-30db>

where snr threshold is the threshold below which the router will retrain to the digital signal line multiplexer (DSLAM). The default is 23db.

Configuration Example

The following example shows a configuration for the dsl snr threshold command:

int atm0
shut
dsl snr threshold 15
no shut
end
sh run
Bulding configuration...
Current configuration : 902 bytes
!
.....
.....
dsl equipment-type CPE
dsl operating-mode GSHDSL symmetric annex B
dsl linerate AUTO
dsl snr threshold 15
debug dsl Command

Use the debug dsl commands to display digital subscriber line (DSL) errors. The no form of this command disables debugging output. Following is the command syntax:

debug dsl

no debug dsl

The following is sample debug dsl output:

router#deb dsl events
router#sh deb
dsl-phy:
events-info are on

ip Whirlpool modem review FIRMWARE ISSUES:
Firmware version 4.0.16 for one tested unit, we had regular disconnections when tested in NZ, as well as a fairly low synch speed of 4068kbps every single time it connected - suspected that this might be some sort of INP framing issue but not had time to investigate - feel free to message adslgeek if you have this, and are happy to do some troubleshooting on this (Or just upgrade to firmware 4.0.17)

Firmware 4.0.17 Stable and had  a good synch speed (same as tested against a Thomson at a similar location).

Firmware version 4.0.18 Specifically fixed a BT issue with instability. A friend of mine tested this firmware in NZ (on ISAM) but this did not seem to make much impact.

This firmware is not available publicly, but I have a copy, so if you require this, just post a message to me directly in the forum, and I am happy to email you this copy.
