Solution Features
MTA Provisioning
The Cisco Subscriber Registration Center (CSRC) v1.5 [with Cisco Network Registrar (CNR) 5.0]
provides a specialized provisioning environment using CSRC component products that help you
automate subscriber service provisioning, such as VoIP, e-mail, Web access, and configuration of
subscriber MTAs, including DOCSIS-compliant MTAs. CSRC 1.5 works in conjunction with CNR to
provide DHCP and TFTP services.
Provisioning system servers include the following:
• DHCP and DNS Server—CSRC provides IP addresses to CPEs and customer IP devices (PCs)
using DHCP. CSRC also provides configuration information to the CPEs that allow them to connect
to the network and access the features that they are authorized for. The provisioning system provides
a DNS server functionality that maps fully qualified domain names (FQDN) to IP addresses.
• TFTP Server—The RFC1350-compliant trivial file transfer protocol (TFTP) server provides the
cable modem with the DOCSIS standard configuration file containing QoS parameters and other
information required for the MTAs to become operational. The TFTP file server can also be used to
provide software upgrade files for the MTAs using the Software Upgrade Filename parameter in the
DOCSIS configuration file.
• Time of Day (TOD) Server—The time of day server provides the MTA with the correct time of day
from Universal Coordinated Time (UTC). The correct time is used to calculate the local time for
time-stamping error logs. The TOD server resides on the same physical machine as the TFTP server.
