Overview of the Cisco 600 Series

Purpose

This chapter provides an overview of the Cisco 600 series customer premises equipment (CPE) devices including the following CPE models:

Cisco 627
Cisco 633
Cisco 673
Cisco 675
Cisco 675e
Cisco 676
Cisco 677
Cisco 678

This chapter also describes the general applications available with the Cisco 600 series CPEs.

Note This chapter documents general product features available in the Cisco 600 series CPEs. Please refer to the Release Notes for the Cisco Broadband Operating System available on CCO for a current list of upgraded software features.

Product Description

The Cisco 600 series CPEs provide home connectivity to a digital subscriber line (DSL) service provider network over a DSL/ATM physical layer. Table 1-1 shows the maximum receive and transmit rates for the Cisco 600 series CPEs:

¹Discrete Multi-Tone
²Carrierless Amplitude and Phase modulation

Note Despite the maximum transmission rates listed above, the actual maximum operative rate is determined by the service provider's central office (CO) equipment. Line length and line conditions can also have a great effect on transmission rate.

System Memory

The Cisco 600 series CPEs are equipped with 4 MB of DRAM.

Environmental Constraints

The Cisco 600 series CPEs operate in an ambient temperature environment of 32\xb0 to 104\xb0 F (0\xb0 to 40\xb0 C) and may be stored in an ambient temperature environment of -40\xb0 to 185\xb0 F (-40\xb0 to 85\xb0 C).

Note Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Ensure that the room in which you operate the CPE has adequate air circulation.

Be careful not to block the air vents on the CPE.

Network Management and Security Applications

The Cisco 627 and Cisco 633 support the following network system management applications:

Telnet server described in "Using Telnet" section.
TFTP server described in "Using a Trivial File Transfer Protocol Server" section.

The general applications supported by the Cisco 673, Cisco 675, Cisco 675e, Cisco 676, Cisco 677, and Cisco 678 are:

DHCP client and server
NAT
Ping
RADIUS
RIP
SNMP
SYSLOG client
Telnet server
TFTP server and client
Traceroute
Web server (HTTP server)

For more information on each of these applications, see the "Configure Applications" section.
