Release Notes

ESIM5700-48

48-Port EFM SHDSL Inverse Multiplexer

Firmware Version 1.01.04

New Features and Enhancements

1) ESIM5700-48 BERT testing functionality has been added in this release. The BSX8000-5 /BSX8000-5R uplink cards must be at version 1.09.01 (or higher) to support BERT testing on the ESIM5700-48 line card. Please refer to the Compatibility Issues section for additional details of which devices are compatible with the ESIM BERT testing feature.

2) Added SNMP MIB support for new Net-to-Net MIBS (version 1.03.03) definitions.

Known Restrictions and Limitations

The following restrictions exist with ESIM5700-48 firmware version 1.03.04:

• 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.
  
• If VLAN tagged Priority traffic (802.1p) is desired, an MTM rule 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

Compatible Firmware Loads

• The ESIM5700-48 must be installed in an IP DSLAM with a BSX8000-5 or BSX8000-5R management card running firmware version 1.07.02 or higher. BERT testing support on the ESIM5700-48 BERT requires BSX firmware version 1.09.01 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 Upgrade procedure at:
  http://www.zhone.com/support/manuals/docs/nettonet/230-0000032_r05.pdf
  

Provisioning Considerations

• If a G.SHDSL link is not achieved, at long distances, when in Rate Adaptive mode, try Fixed Rate mode by setting the Min. and Max. Data Rates to the same value.
  
• Currently if any of 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 that the ESIM5700 link rate is reported in terms of data rate, whereas 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 reported rates on the ESIM5700-48 will give you information in the same terms as that reported by the SIM2000-24 card.
  
• If is recommended that the CPE connecting to the ESIM5700-48 be configured in Adaptive Rate mode, even if the ESIM5700-48 is configured for Fixed Rate mode.
  

Loop Bonding

• ESIM5700-48 firmware version 1.00.00 (or above) is required for SHDSL 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 SHDSL Loop Bonding Product-to-Product Feature Compatibility document for a complete list of loop bonding capable products and required firmware versions.

Reseting Remote Devices

• The ETHX-21xx and ETHX-33x4 Series devices cannot be remotely reset via the ESIM5700-48 card. All ETHX-21xx and ETHX-33x4 models must be remotely reset by first logging into the ETHX device and resetting it from there.
  
• In order to remotely reset Zhone's SNE2040G-S (SHDSL CPE) via the IPD web management, the SNE2040G-S must have firmware version 6.00.00 or higher.
  

ESIM5700-48 to SNE20x0 BERT Testing
Currently the SNE firmware does not support bi-directional BERT testing; only Unidirectional BERT testing is supported. When displaying BERT results for an SNE20x0 device, an "N/A" will be displayed under the "CPE" and "CPE Errored bits" columns to indicate that BERT testing in that direction is not supported. The results will also show "N/A" after a test is completed if the ESIM5700-48 card cannot obtain results from the CPE for any reason. The SHDSL line will drop and retrain at the end of the test.

ESIM5700-48 to SIM2000-24 BERT Testing
The SIM2000 card requires 2.04.04 firmware or greater for compatibility with the ESIM5700-48 line card BERT testing functionality. The SHDSL line will drop and retrain at the end of the test.

ESIM5700-48 to ETHX-21xx BERT Testing
ESIM5700-48 to ETHX-21xx BERT Testing is not supported at this time. All testing is blocked and an error message is generated indicating the ETHX-2100 is incompatible with the current implementation of BERT testing on the ESIM5700-48 line card.

Additional Notes

To pass VLAN traffic through the ESIM5700, an additional VLAN Rule should be configured in web management to allow all VLAN tagged traffic from 1 to 4085 to pass through the DSL port. This rule should be set as follows:
Rule # 2 Yes tagged 1 4085 keep tag (all other columns can be left in default).

If untagged traffic is also desired, leave VLAN Rule 1 active.

Firmware 1.01.03 added support for sub-rate i=1 for TCPAM16 at rates 2312 and below. This provides more rates for better compatibility with the older SNE2000-S units. The following guidelines apply:

• For the maximum rate on a port connected to an older SNE2000 running version 4.03.50 or older, set the ESIM5700 port to 2312.
  
• For an ESIM5700 port connected to an older SNE2000, never set the ESIM port speed at 2304 or higher than 2312. Sub-rate 1 is not supported for TCPAM-32.
  
• The resultant port link speed will be (n * 64 kbps) plus (i * 8 kbps) where 'n' is at least 3 and 'i' is 0 or 1. 'n' is the primary rate and 'i' is the sub-rate.
  

The Conexant DSP version is: shdslp2_e309.03.120_Api_672
