Basic principles
| Protocol | Usage | Provisioning of |
|---|---|---|
| TR-69 | protocol for remote management of customer-premises equipment (CPEs) | CPEs only! |
| PPPoE | The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside Ethernet frames. (wikipedia) | speed provisioning of any device (DSL, PGON, AE, ..) |
The problem
TR-69 is a provisioning protocol for CPE's only. This implies there is now standardised way of how to set Modem speed rates (e.g. Downstream/Upstream rate 100MBit/s to 10MBit/s). Many operator address this by using a quick-and-dirty method of setting internet speeds at the OLT directly via CLI. The next logical step is easy but also dirty: using the CRM to somehow "connect via telnet or SSH and push the required speed rates via CLI (or better SNMP)". This will work but it comes at a high price, imagine:
disadvantages for setting the modem speed via CLI directly at the OLT:
- vendor specific CLI commands (or SNMP MIBs) makes life hard for a generic implementation approach
switching OLT vendor will cause pain! - ONU –> OLT port mapping required
support team needs knowledge of FTTH connection circuits (ineffective/bad workflow!) - potential config race conditions / hazards
Assume you are connected via SSH towards your OLT, while the provisionig system pushes also config changes via telnet/SSH. This could lead to race conditions, especially while saving configs.
