Deployment of Cisco DOCSIS-based transponders is similar to provisioning
standard subscriber cable modems and MTAs. However, there are certain exceptions
owing to the transponder being a test device. For example, take care when
provisioning that the transponder is not invoiced in the billing system or mistakenly
blocked. Cable operators will want to adapt the deployment strategy to fit their
unique operational landscape. The introduction of a new device type in the DOCSIS
network touches several OSS systems and disciplines whose participation is needed
for successful and timely deployment.

Security

Different security methods are used to ensure network integrity. Some common
issues are:
Subscriber account (where the transponder is the subscriber) may be required for

each transponder
The transponder MAC address may have to be pre-loaded into the CMTS

MAC filtering may have to be modified to allow MAC addresses starting with

00:10:3F:xx:xx:xx to be registered and 00:26:97:xx:xx:xx to be registered
For SNMP access, UDP ports 161 and 162 must not be blocked

Firewalls must allow communication between the cable modem and the various

servers
