Product Overview
This chapter provides an overview of the Cisco 6260 Digital Subscriber Line (DSL) Access Multiplexer
(DSLAM) and its related components, collectively known as the Cisco 6260 system. This chapter contains
the following sections:
• Introduction to the Cisco 6260 System, page 1-1
• Cisco 6260 System Overview, page 1-10
• Management Software, page 1-49
1.1 Introduction to the Cisco 6260 System
The Cisco 6260 system is part of the Cisco DSL product family that provides end-to-end service by
carrying voice or data traffic, or both, between a subscriber’s home or office, a telephone central office
(CO), and various networks beyond. The Cisco 6260 system sends and receives subscriber data (often
Internet service) over existing copper telephone lines, concentrating all traffic onto a single high-speed
trunk for transport to the Internet or a corporate intranet. Before traveling over telephone lines to the
DSLAM at the CO, data is modulated by xDSL customer premises equipment (CPE) devices, which are
connected to PCs or routers at the subscriber site.
The Cisco 6260 system may include the following components:

1.1.2.3 IMA Configuration
The DS3+T1/E1 IMA NI-2 card uses inverse multiplexing over ATM (IMA) technology to aggregate
multiple low-speed links into one larger virtual network trunk or IMA group. An inverse multiplexer
appears to your ATM switch router as one logical pipe. IMA provides you with modular bandwidth to
access the ATM network between T1/E1 and DS3/E3 rates. The Cisco 6260 system allows you to
combine up to eight E1 lines to form an IMA group.
Cisco 6260 Hardware Installation Guide
1-4
OL-2365-02
Chapter 1 Product Overview
IMA breaks up the ATM cell stream, distributes the cells over the multiple physical links of an IMA
group, and recombines the cells into a single stream at the other end of the connection. The ATM cells
are distributed in a round-robin fashion over the physical links of the IMA group, recombined at the
receiving IMA group, and passed in their original form to the ATM layer (see Figure 1-2). Using the
multiple links of an IMA group increases the logical link bandwidth to approximately the sum of the
individual link rates. The physical links should be nominally the same length to avoid excessive
intragroup delay. We recommend that all of the links in an IMA group be bundled together between the
source and the destination.

E1 I/O modules have eight ports. You can use the eight ports on the E1 I/O modules as independent ATM
links or in the IMA mode. The following bullets are examples of possible IMA groups, independent ATM
links, and mixed modes. In examples of IMA groups, two links are assumed per group.
• Four IMA groups with any combination of eight links
• Three IMA groups and up to two independent ATM links
• Two IMA groups and up to four independent ATM links
OL-2365-02
• One IMA group and up to six independent ATM links
• No IMA group and up to eight independent ATM links
The E1 (1.544 Mbps) IMA port adapters provide network trunk or subtend connectivity and are used for
intercampus or wide-area links. The E1 IMA port adapters support unshielded twisted-pair (UTP)
connectors. The order of assignment of links to an IMA group is not restricted.
The IMA group interfaces use a naming convention different from those used by the other interfaces in
the system. IMA group interfaces are named with the convention atm<slot>/ima<group>, where <slot>
is the slot number for the DS3+T1/E1 IMA NI-2 card and <group> is the IMA group number from 0 to
3. Table 1- 1 lists the interface naming conventions.

1.1.2.4 Subtended Network Configuration
The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a
subtended network.
NoteFor information on enabling redundancy in subtended network configurations, see the “Redundancy in
Subtended Configurations” section on page 1-41.
A subtended network configuration
• Services and aggregates the data from one or more Cisco 6260 chassis into a subtending host chassis
to take advantage of the data network interface on the subtending host chassis.
• Reduces the number of ATM edge-switch ports required to terminate the chassis.
• Supports a Cisco 6260 system with a POTS splitter and a Cisco 6260 system without a POTS
splitter configuration.
A subtended network configuration supports the following features:
• Four arbitration priorities, one for each quality of service (QoS) level. The supported QoS service
levels are
–
Constant bit rate (CBR) for rate-limited services that require guaranteed bandwidth and
bounded delay
–
Variable bit rate real time (VBR-rt) for delay-sensitive voice and video services
1-6
–
Variable bit rate nonreal time (VBR-nrt) for high-priority data services
–
Unspecified bit rate (UBR) for low-priority data services
• Explicit forward congestion indication (EFCI) marking for available bit rate (ABR) service support.
• Guaranteed frame rate (GFR).

Chapter 1 Product Overview
• Tree or daisy chain topology configurations for E3 subtended Cisco 6260 chassis.
• Star topology configurations for E1 or IMA group subtended Cisco 6260 chassis.
• Daisy chain configurations for OC-3c subtended Cisco 6260 chassis.
• Fair access to the trunk port for each subtended chassis.
• A network trunk port that operates as fast as any subtended link.
The NI-2 card provides one of following types of subtended network connections:
• An E3 ATM interface
• A high-speed OC-3c optical ATM interface that supports single-mode fiber (SMF)
• A high-speed OC-3c optical ATM interface that supports multimode fiber (MMF) short range
• Up to eight E1 interfaces when you are using the DS3+T1/E1 IMA NI-2 card in conjunction with
• Up to four IMA interfaces when you are using the DS3+T1/E1 IMA NI-2 card in conjunction with

1.1.2.4.1 Subtended Network Configuration with DS3/2DS3 NI-2 Cards
In a subtended network configuration using DS3/2DS3 NI-2 cards, you can subtend a Cisco 6260
chassis to four tiers, with up to 12 chassis, all connecting through one subtending host chassis to the
ATM backbone.
When the DS3/2DS3 NI-2 card is installed in the Cisco 6260 chassis, it adopts E3 functionality.
Figure 1-3 shows E3-configured Cisco 6260 systems subtended in a combined subtending tree topology
with daisy chain. The subtending host chassis at the top of the subtending tree connects directly to the
ATM switch. The middle two Cisco 6260 chassis in the lowest level are daisy chained. You make
network interface connections at the I/O module that is installed on the front of the Cisco 6260 chassis.

For each chassis in a subtended network configuration to have fair access to the shared network trunk,
the chassis must have a unique ID number. The subtending host chassis places this ID number in the GFC
field of the ATM header of each cell; this ID number is then used to forward cells up the tree to the
network trunk.
NoteYou can subtend Cisco 6260 chassis with DS3/2DS3 NI-2 cards in a continuous daisy chain. However,
a daisy-chained subtending scheme is not optimal for data throughput for Cisco 6260 chassis that use
DS3/2DS3 NI-2 cards.
Cisco IOS software does not manage the primary Cisco 6260 chassis and all subtended Cisco 6260
chassis as a single large Cisco 6260 system. Each Cisco 6260 chassis supports an independent Cisco IOS
processor and MIBs.

1.1.2.4.2 Subtended Network Configuration with DS3+T1/E1 IMA NI-2 Cards
In a subtended network configuration using DS3+T1/E1 IMA NI-2 cards, you can subtend Cisco 6260
systems in a star topology. The eight E1 links can be used as network trunk or subtend interfaces or can
be combined into trunk or subtend IMA groups in the following two ways:
• E1 IMA group or E1 User-Network Interface (UNI) as the network trunk with seven subtended node
chassis
NoteIf you are using an E1 trunk to the network, the trunk connection originates at one of the RJ-48
receptacle connectors on the E1 I/O module. Therefore, you can have only seven subtended
node chassis.
• Up to seven individual E1 interfaces or up to four IMA groups, or a combination of the two
Figure 1-4 shows an example of a subtended network with a star topology. The subtending host chassis
in the middle of the star topology connects directly to the ATM switch.

that allows modular insertion and removal of various field-replaceable units (FRUs). The Cisco 6260
system includes
• A card compartment with 32 slots: 30 slots for xTU-C line cards and two slots for NI-2 cards
• A set of connectors that serve subscriber lines with or without POTS splitters
• An I/O module
• Compartments for two PEMs, two fan trays, and air filters.
See Figure 1-1 for the location of the system components in the Cisco 6260 chassis.
