Terminology
An Optical Network Termination (ONT) is a type of Optical Network Unit (ONU)
designed for single-subscriber applications. The GPON standards use the term ONT by
default unless a distinction is necessary. This documentation uses both terms, identifying
any units that use pluggable line cards as modular. The BLM 1500 software uses ONT
to generically indicate all types.
Fabric and application printed circuit boards in the BLM 1500 are referred to as
application packs in the software and in this documentation.

Recovery Requirements
Calix First Line Local Support (FLS) or Second Line Local Support (SLS) and the customer
will work to recover the system and return it to normal functioning in less than 60 minutes.
Personnel involved
In emergencies, Local Support, a Service Delivery Manager (SDM), Global Support, Front
Office and Technical Staff, a Recovery Leader, and Second Line Support engineers might be
involved. The customer may also be present.
When handling a non-emergency CSR, Local and Global Support are usually involved, and
an SDM might also be involved with a Hot CSR.
On site system access
Calix Local Support must be provided with all appropriate IP addresses, users, and
passwords required to log into the faulty system.
Remote system access
Remote Support Gateway (RSG) access must be provided to the engineers involved in the
case.
An RSG installation makes it possible to reach all nodes in a customer network and to
provide support services like updates and upgrades from a desk in any Calix office connected
to the global Calix Network. Almost all systems delivered by Calix to the customer network
are accessible remotely, for significant customer cost savings.
Tools for recovery
Go-To-Meeting and Remote Desktop over the RSG are the most important support tools
when dealing with emergencies. To facilitate information flow, SMS/Primus® and IBM®
Lotus® Sametime® connect availability are crucial during the service recovery activity. No
other remote access methods are supported by the Third Line Support organization.
Fault reporting
FLS must call the Global Front Office when a fault is present. Report all activities to the next
level of support for a follow-up Root Cause Analysis (RCA), to determine the source of the
problem. Refer to Trouble Escalation (on page 89) for escalation and data collection
procedures.

TAP301 On-site Craft Connection Failure
1. Can you get a user prompt? For example:
BLM1500 - Broadband Loop Multiplexer
Copyright 2001-2007 Entrisphere Inc.
Fabric & Control Processor (ttyp0)
BLM1500_TPML5_01 (BLM1500_TPML5_01)
booted Thu Aug 20 00:22:07 SGT 2010, up for 674:11:23
user:
If yes, go to Step 2.
If no, go to Step 3.
2. Ensure that you are connecting to the correct chassis and using the correct login. You
might have been locked out, by the administrator or because of too many failed login
attempts (typo or incorrect password). Contact the appropriate department to ensure
your login is still valid.
Did this correct the problem?
If yes, STOP. You have completed this procedure.
If no, contact your next level Support.
3. Can you ping the IP address?
If yes, are you connecting on port 23? If so, contact your next level of Support.
If no, go to Step 4.
4. A traceroute should help you determine where the connection is failing. Adding a static
route to that link usually corrects the issue. If you are attempting to connect directly from
your PC to the Ethernet port on the front of the FAB3 pack, make sure you have a static
IP address in the same subnet as the FAB interface.
Did this correct the problem?
If yes, STOP. You have completed this procedure.
If no, contact your next level Support.

TAP302 Remote Craft Connection Failure
1. Is your remote Craft (serial) connected through a MODEM, an I/O LAN, or a router
Auxiliary port?
If a modem, go to Step 2.
If an I/O LAN type device, go to Step 4.
If a router Auxiliary port, go to Step 6.
2. Are you connecting to the MODEM?
If yes, go to Step 3.
If no, troubleshoot your connection software, modem port, and management
network.
3. Ensure that the MODEM is configured as follows:
9600 Baud
8 Data bits
No parity
One stop bit
Flow control off
Did this give you access?
If yes, go to Step 8.
If no, contact your next level Support.
4. Open a Terminal Emulator (such as telnet, Hyperterminal, PuTTY, or TeraTerm).
Ensure that you are using the correct IP address and port number for the BLM 1500 to
which you are attempting to connect.
5. Ensure that the I/O LAN port is configured as follows:
9600 Baud
8 Data bits
No parity
One stop bit
Flow control off
Did this give you access?
If yes, go to Step 8.
If no, contact your next level Support.
