Release Notes

ESIM5700-48

48-Port EFM SHDSL Inverse Multiplexer

Firmware Version 1.01.01

New Features and Enhancements

Enhancements:

1) The ESIM5700-48 has increased the supported Maximum line rate from 2.3Mbps to 5.696Mbps when connected to capable CPE units. Data rates from 192Kbps to 5.696Mbps are supported in 64Kbps increments.

2) Added configuration of line training operational mode. Current and Worst case Target Margins modes are supported. If a mixture of the two are used it is considered Both or Mixed mode. The default setting of "Current Condition" "5" is recommended

Bug fixes:

Accurate use of VLAN 4085 in all MTM rules has been corrected.

Known Restrictions and Limitations

Currently the ESIM5700-48 does not support BERT. This feature will be added in a future release of code.

In order to maintain proper traffic flow, at least one MTM (Multi-media Traffic Management) (QoS) rule of any kind must be enabled at all times on each SDSL port. By default, there is one MTM VLAN rule enabled. This rule will pass all untagged traffic through the DSL port. To pass VLAN traffic through the ESIM5700 an addition VLAN Rule can be configured in web management as follows:
Rule # 2 Yes tagged 1 4085 keep tag, all other columns can be left in default. This VLAN Rule will allow all VLAN tagged traffic from 1 to 4085 to pass through the DSL port. If untagged traffic is wanted, leave VLAN Rule 1 active.

If VLAN tagged (802.1p) traffic is desired, an MTM rule of any kind must be configured. VLAN Priority "P" tags must be configured in the Upstream network in order for Priority settings to function in the Downstream direction. The ESIM5700 will add "P" tags for traffic flowing Upstream from the modem.

The ESIM5700-48 can only be configured in Provider mode. It will not support
Subscriber mode.

Compatibility Issues

The ESIM5700-48 must be installed in an IP DSLAM with a BSX8000-5 management card running firmware version 1.07.02 or higher.

The MUM2000-2 does not support the ESIM5700-48.

For optimal compatibility, Zhone recommends maintaining ESIM5700-48 firmware
at the latest available version. To upgrade the ESIM5700-48 card, refer to the Uprgrade procedure at http://www.zhone.com/support/manuals/docs/nettonet/230-0000032_r05.pdf

If a G.SHDSL link is not achieved, at long distances, when in Rate Adaptive mode, try Fixed rate mode by setting Min and Max Data Rates to the same value.

Currently if the following speeds are desired in Fixed rate mode then the line's Constellation should be changed from Adaptive to TCPAM_32 - 3648, 3584, 3456, 3264, or 3200 Kbps.

The Fixed rate of 3776Kbps is not supported.

The ESIM5700-48 differs from the SIM2000-24 in it's link rate reporting in that it reports link rate in terms of data rate where the SIM2000-24 reports link rate in terms of line rate. Data rate is typically 8Kbps less than line rate. Therefore, adding 8Kbps to all rates on the ESIM5700-48 will give you information in the same terms as the SIM2000-24.

If is recommended that the CPE connecting to the ESIM5700-48 be configured in
Apaptive Rate mode, even if the ESIM5700-48 is configured for Fixed rate mode.

ESIM5700-48 firmware version 1.00.00 (or above) is required for SDSL loop bonding. The SHDSL equipment at both ends of a subscriber loop must be SHDSL loop bonding capable in order for the loop bonding feature to be utilized. Refer to Zhone's SDSL Loop Bonding Product to Product Feature Compatibility document at http://www.zhone.com/support/manuals/docs/AZ/COMP-A2-GK42-00.pdf for a complete list of loop bonding capable products and required firmware versions.

The ETHX-SHDSL devices cannot be remotly reset via the ESIM57000 card. All ETH-SHDSL and ETHX-SHDSL-LT devices can be remotly reset by logging into that device first and resetting it from there. In order to remotely reset Zhone's SNE2040G-S (SHDSL CPE) via web management, the SNE2040G-S must have firmware version 6.00.00 or higher.

The Conexant DSP version is: shdslp2_e309.03.109_Api_665
