Product Overview

The Cisco 6015 system is part of the Cisco digital subscriber line (DSL) product family that provides end-to-end service by carrying data between a subscriber's home or office and a network, which can be managed by one of the following:

Competitive local exchange carrier (CLEC)
Incumbent local exchange carrier (ILEC)
International post, telephone, and telegraph (PTT)

The Cisco 6015 system is also designed for use in multitenant/multiple dwelling units (MTU/MDUs) and can be deployed in either a commercial or an outside-plant environment, such as at a digital loop carrier (DLC) remote site.

Note Before you install a Cisco 6015 system in an outside-plant environment, verify that the remote terminal enclosure meets the following compliance requirements: GR-487, UL 50 Type 4X, EN60529 IP 55, and NEMA 4X.

Figure 1-1 details a high-level network architecture diagram of a Cisco 6015 installed in an outside-plant environment.

Figure 1-1 Network Architecture for a Cisco 6015 in an Outside-Plant Environment

The Cisco 6015 system sends and receives subscriber data (often Internet service) over existing copper telephone lines and concentrates all traffic onto a single high-speed trunk for transport to the Internet or a corporate intranet. Asymmetric digital subscriber line (ADSL) or single-pair high-speed digital subscriber line, also known as symmetric high bit rate digital subscriber loop (SHDSL), customer premises equipment (CPE) devices, which are connected to PCs or routers at the subscriber site, modulate data so that it can travel over telephone lines to the Cisco 6015 system.

Note For detailed information on the various components in the Cisco DSL product family (including central office [CO] and CPE devices), see the "Related Documentation" section.

The Cisco 6015 system includes the following hardware and software components:

Cisco 6015 chassis—Deployed with a standard network interface-version 2 (NI-2). The following components will be installed in the chassis:

Quad-port flexi ATU-C line cards (4xflexis), octal-port DMT ATU-C line cards (8xDMTs—both commercial and outside-plant versions), octal-port DMT ATU-C over ISDN line cards (8xDMT over ISDN), octal-port single-pair high-speed digital subscriber line, also known as symmetric high bit rate digital subscriber loop (G.SHDSL) line cards (8xG.SHDSLs)

Note The 4xflexi, 8xG.SHDSL, commercial environment 8xDMT, and the 8xDMT over ISDN can be used only in a commercial environment. They cannot be used in an outside-plant environment. For line card intermixing information, see the "Cisco 6015 Cards and Modules" section.

DS3+T1/E1 inverse multiplexing over ATM (IMA) NI-2 card, the industrial temperature (ITEMP) DS3+T1/E1 IMA NI-2 card, or the OC-3c/OC-3c NI-2 card

Note The OC-3c/OC-3c NI-2 card can only be used in a commercial environment. The ITEMP DS3+T1/E1 IMA NI-2 card is the only NI-2 card designed for use in an outside-plant environment.

Fan module
DS3+T1 Input/Output (I/O) module or E1 I/O module
DSL interface module
DC power entry module (PEM)

AC/DC converter (optional if you need to convert AC power to usable DC power)

Note The AC/DC converter can be used only in a commercial environment. It cannot be used in an outside-plant environment.

Plain old telephone service (POTS) splitter (optional). The POTS splitter is a passive device that supports simultaneous voice (basic telephone service) and data services and is available from Cisco Ecosystem partners

Note Third-party POTS splitters can be installed in a Cisco 6015 with a POTS splitter configuration. Please verify the compatibility with your Cisco representative.

For POTS splitter information, refer to the vendor documentation.

A system configuration using 8xDMTs or 8xDMT over ISDNs requires a POTS splitter that expands the system capacity to 48 subscriber ports. Depending on the POTS splitter selected for your configuration, the installation of an additional POTS splitter may be necessary.

Management software—Provisions and manages the Cisco 6015 system.

Cisco IOS—A command-line interface (CLI) that is available for network element provisioning.
Cisco DSL Manager (CDM)—A graphical user interface (GUI) designed to configure and manage the 6xxx series of Cisco IOS software-based DSL access multiplexers (DSLAMs). CDM provides the following areas of network management—fault, configuration, performance, and security. CDM runs with the Cisco Element Manager Framework (EMF); both are installed on Sun workstations.

Cisco EMF is based on an object model in which network elements or modules represent the managed entity. Each object is defined by a class and specific attributes. An object can represent a network element or a more abstract entity such as a link relationship, a network, or a container such as a site, shelf, or region.

Note See the "Hardware Specifications" section for minimum software and network management release requirements per Cisco 6015 chassis component.

8xDMTs—Two versions: one for a commercial environment and one for an outside-plant environment
8xG.SHDSLs—Use only in a commercial environment

AC/DC converter—Optional if you use AC power; use only in a commercial environment

In this configuration, the Cisco 6015 connects directly to the main distribution frame (MDF) in a commercial environment or the enclosure protection block in an outside-plant environment.

Figure 1-3 shows the components that can be used in a Cisco 6015 without a POTS splitter configuration.

Figure 1-3 Cisco 6015 Without a POTS Splitter Configuration

Note In North America, the DS3+T1 I/O module will be installed in the chassis. In world-wide environments, the E1 I/O module will be installed in the chassis.

1.1.2.3 Subtended Network Configuration

A subtended network configuration

Services and aggregates the data from one or more Cisco 6015 chassis into a subtending host chassis to take advantage of the data network interface on the subtending host chassis.

Note The Cisco 6015 can also serve as the subtending host chassis to, or a subtended node chassis from, the Cisco 6100, Cisco 6130, Cisco 6160, and Cisco 6260.

Provides additional benefits by reducing the number of ATM edge-switch ports that are required to terminate the chassis.
Supports both a Cisco 6015 with a POTS splitter and a Cisco 6015 without a POTS splitter configuration.

The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a subtended network.

The following subtended network configurations are supported:

DS3 trunk with up to eight individual T1/E1 subtended interfaces or up to four IMA groups, or a combination of the two
Daisy chain configuration for OC-3c subtended Cisco 6015 chassis.
Eight T1 IMA trunked and subtended interfaces

T1 IMA group or T1 User-Network Interface (UNI) as the trunk
Up to seven individual T1 interfaces or up to four IMA groups, or a combination of the two

Note The use of a T1 or IMA group trunk disables the DS3 interface.

Eight E1 IMA trunked and subtended interfaces

E1 IMA group or E1 UNI as the trunk
Up to seven individual E1 interfaces or up to four IMA groups, or a combination of the two

The following sections detail the different types of subtending network connections.

1.1.2.3.1 Subtended Network Configuration with the DS3+T1/E1 IMA NI-2 Card and the ITEMP DS3+T1/E1 IMA NI-2 Card

In a subtended network configuration using a DS3+T1/E1 IMA NI-2 card or an ITEMP DS3+T1/E1 IMA NI-2 card, you can subtend up to 12 Cisco 6015 chassis through a daisy-chain configuration of IMA links, or a star configuration of IMA links. The subtending chassis connect through one subtending host chassis with a DS3 connection to the ATM backbone.

You can also make the host chassis ATM trunk connection through a T1 or IMA group, but that disables the DS3 interface. See the "IMA Configuration" section for more information on using IMA group or individual links.

Note The Cisco 6015 can also serve as the subtending host chassis to, or as a subtended node chassis from, the Cisco 6100, Cisco 6130, Cisco 6160, or Cisco 6260.

Figure 1-4 shows an example of a subtended network with a star topology. Subtended Network—Star Topology. The subtending host chassis in the middle of the star topology connects directly to the ATM switch. With a DS3 trunk, you can have up to eight subtended node chassis connected to the subtending host chassis.

Figure 1-4 Star Topology for Cisco 6015 Subtended Network

Note Consult with your network architect or Cisco customer service representative for examples of other subtending topology configurations using the DS3+T1/E1 IMA NI-2 card and the ITEMP DS3+T1/E1 IMA NI-2 card.

1.1.2.3.2 IMA Configuration

The DS3+T1/E1 IMA NI-2 card uses IMA technology to aggregate multiple low-speed links into one larger virtual 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 or E1 and DS3 or E3 rates. The Cisco 6015 allows you to combine up to a maximum of eight T1 or E1 lines to form an IMA group.

IMA breaks up the ATM cell stream, distributes the cells over the multiple physical links of an IMA group, then 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 1-5). 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 intra-group delay. Cisco recommends that all of the links in an IMA group be bundled together between the source and the destination.

Figure 1-5 Inverse Multiplexing and Recombining of ATM Cells Through IMA Groups

The T1 and E1 IMA I/O modules have eight ports. You can use the eight ports on the T1 and E1 IMA 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. Examples of IMA groups assume two links 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
One IMA group and up to six independent ATM links
No IMA group and up to eight independent ATM links

The T1 (1.544 Mbps) and E1 (2.048 Mbps) IMA port adapters provide trunk or subtend connectivity and are used for intercampus or wide-area links. The T1 and 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 modified naming convention from the other interfaces in the system. These 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.

Table 1-1 Interface Naming Conventions

Interface	Name
DS3 link	atm0/1
T1/E1 link 0	atm0/2
T1/E1 link 1	atm0/3
T1/E1 link 2	atm0/4
T1/E1 link 3	atm0/5
T1/E1 link 4	atm0/6
T1/E1 link 5	atm0/7
T1/E1 link 6	atm0/8
T1/E1 link 7	atm0/9
IMA group 0	atm0/ima0
IMA group 1	atm0/ima1
IMA group 2	atm0/ima2
IMA group 3	atm0/ima3

1.1.2.3.3 Subtended Network Configuration with OC-3c/OC-3c NI-2 Cards

In a subtended network configuration using OC-3c/OC-3c NI-2 cards (SMF or MMF), you can subtend up to 12 OC-3c configured chassis in a daisy chain, all connecting through one subtending host chassis to the ATM backbone (see Figure 1-6).

Note The Cisco 6015 can also serve as the subtending host chassis to, or as a subtended node chassis from, the Cisco 6100, Cisco 6130, Cisco 6160, or Cisco 6260.

Figure 1-6 Daisy Chain Topology for OC-3c Interfaces

1.2 Cisco 6015 Chassis Overview

The Cisco 6015 chassis uses a front-access, six-slot multiport line-card architecture capable of supporting up to 48 xDSL ports that are connected either directly or through a POTS splitter.

Note For hardware specifications for the Cisco 6015, see the "Cisco 6015 System Specifications" section on page A-2.

The chassis supports the following hardware components:

Up to six 4xflexi, 8xDMT, 8xG.SHDSL, or 8xDMT over ISDNs
DS3+T1/E1 IMA NI-2 card, ITEMP DS3+T1/E1 IMA NI-2 card, or OC-3c/OC-3c NI-2 card
DS3+T1 or E1 I/O module
DSL interface module
DC PEM
Fan module

Note You can purchase blank faceplates for empty Cisco 6015 module slots.

The 8xDMT over ISDN can be used only in a Cisco 6015 system with a POTS splitter configuration.

Figure 1-7 identifies the Cisco 6015 card and module slots. Each line card slot on a chassis is numbered along the left edge of the card slot (slots 1 through 6). In the guide illustrations, the slot numbers are shown on the cards for easy reference and readability. These slots are referred to in subsequent sections of this chapter and elsewhere in this guide.

The following sections detail these Cisco 6015 hardware components:

1.2.1 Cisco 6015 Cards and Modules

This section contains the following information about Cisco 6015 cards and modules:

The Cisco 6015 chassis supports line card intermixing. However, mixing cards with different types of encoding (ADSL or SHDSL) on the same side of the chassis could result in decreased performance of the loop due to overlapping frequency spectrums. To minimize potential performance degradation in the binder, install ADSL and SHDSL line cards in separate halves of the chassis. For example, if you install 4xflexis on the left side of the chassis (slots 1 to 3), install 8xSHDSLs on the right side of the chassis (slots 4 to 6).

1.2.1.1 4xflexi Overview

The 4xflexi

Supports CAP, DMT, or G.lite line encoding.
Supports four ADSL modem connections.
Converts ADSL modulation from the line into digital data streams to and from the NI-2 card.
Negotiates the line rate with the CPE when it trains and bases the rate on line quality and distance.

Note The 4xflexi cannot be used in an outside-plant environment.

For line card intermixing information, see the "Cisco 6015 Cards and Modules" section on page 1-11.

If provisioned, the 4xflexi rate adapts to the maximum bit rate negotiable on the line. The maximum bit rate settings are provisioned in the management software.

Note For hardware specifications for the 4xflexi, see the "4xflexi Specifications" section A-3.

The Cisco 6015 chassis can include up to six 4xflexis for a total of 24 ADSL modem connections.

The edge connector key, located on the rear of the 4xflexi, connects the 4xflexi to the backplane of the chassis. You can install only the edge connector key with seven notches in the Cisco 6015.

1.2.1.4 8xG.SHDSL Overview

The 8xG.SHDSL

Is designed for use in a Cisco 6015 without a POTS splitter configuration.
Supports eight G.SHDSL modem connections.
Supports trellis coded pulse amplitude modulation (TC-PAM) line encoding.
Converts G.SHDSL modulation from the line into digital data streams to and from the NI-2 card.
Supports fixed and adaptive rate modes.

Note The 8xG.SHDSL cannot be used in an outside-plant environment.

For line card intermixing information, see the "Cisco 6015 Cards and Modules" section on page 1-11. For hardware specifications for the 8xG.SHDSL, see the "8xG.SHDSL Specifications" section A-6.

The Cisco 6015 chassis can include up to six 8xG.SHDSLs for a total of 48 SHDSL modem connections.

Note The 8xG.SHDSL line card supports multiple line rates ranging from 72 kbps to 2312 kbps in fixed mode. In rate adaptive mode, the 8xG.SHDSL line card supports rates ranging from 2312 kbps to 200 kbps in 64 kbps decrements. In rate adaptive mode, line rate is negotiated and then locked when the line trains.

1.2.1.5 DS3+T1/E1 IMA NI-2 Card Overview

The DS3+T1/E1 IMA NI-2 card can be installed in the following environments:

Commercial—Use the DS3+T1/E1 IMA NI-2 card (part number NI-2-DS3-T1E1)
Outside plant—Use the ITEMP DS3+T1/E1 IMA NI-2 card (part number NI-2-DS3-T1E1-H)

The DS3+T1/E1 IMA NI-2 card provides a high-speed connection for aggregated data traffic from the xTU-C line cards. The NI-2 card performs central processor, host, and system controller functions. The NI-2 card runs and is controlled by Cisco IOS software.

The DS3+T1/E1 IMA NI-2 card performs the following system tasks:

Contains the ATM switch fabric
Controls timing through an internal clock or BITS interface, or from an ATM interface (DS3, T1, or E1)

Note The BITS interface is connected through a header that is located on the back of the chassis.

Provides CO facility alarm input
Provides operating status visual indications
Performs subtending and other control functions

The ITEMP DS3+T1/E1 IMA NI-2 card motherboard and IOS daughter card are populated with industrial temperature components so that the NI-2 card can operate in an outside-plant environment.

The NI-2 card operation mode (DS3/T1 or E1) is determined by the type of I/O module, DS3+T1 or E1, installed in the Cisco 6015 chassis. For more information on the I/O modules, see the "I/O Module Overview" section.

Note For hardware specifications for the DS3+T1/E1 IMA NI-2 card, see the "DS3+T1/E1 IMA and ITEMP DS3+T1/E1 IMA NI-2 Cards Specifications" section.

Figure 1-13 shows a close-up of the DS3+T1/E1 IMA NI-2 card faceplate.

Note The only cosmetic difference between the DS3+T1/E1 IMA NI-2 card and the ITEMP DS3+T1/E1 IMA NI-2 card is the word "ITEMP" silkscreened on the card faceplate.

1.2.1.6 OC-3c/OC-3c NI-2 Card Overview

The OC-3c/OC-3c NI-2 card

Connects to the xTU-C line cards through point-to-point serial data buses on the backplane
Performs central processor, host, and system controller functions
Contains the ATM switch fabric
Supports the aggregation of up to 12 subtended node chassis configured for OC-3c operation in a daisy chain configuration.
Provides an OC-3c subtend interface through optical connectors located on the NI-2 card faceplate.
Controls timing and redundancy

Note The BITS interface is connected through a header located on the back of the Cisco 6015 chassis.

The OC-3c/OC-3c NI-2 card can only be used in a commercial environment.

Provides CO facility alarm relay contact interfaces and an ACO button
Provides operating status visual and audible indications
Performs subtending and other control functions
Provides the network OC-3c WAN trunk interface through connectors located on the NI-2 card faceplate. The following two versions of the OC-3c/OC-3c NI-2 card are available to support the WAN trunk interface:

SMF intermediate range.
MMF short range.

Note The OC-3c/OC-3c NI-2 card cannot be used in an outside-plant environment.

Use of the OC-3c/OC-3c NI-2 card in the Cisco 6015 disables whichever I/O module is installed in the chassis. Therefore, neither I/O module will affect the OC-3c/OC-3c NI-2 card operation in the Cisco 6015.

For hardware specifications for the OC-3c/OC-3c NI-2 card, see the "OC-3c/OC-3c NI-2 Card Specifications" section.

The OC-3c/OC-3c NI-2 card functions are managed by Cisco IOS software. The IOS software operates and integrates controller, network trunk, and subtending functionality from this single NI-2 card.

The SMF and MMF OC-3c/OC-3c NI-2 cards operate in conjunction with network interfaces that are supplied by optical interface connectors on the OC-3c/OC-3c NI-2 card faceplate. The OC-3c/OC-3c NI-2 card faceplates have two optical connector pairs:

The top optical connector pair receives OC-3c ATM network transmit and receive trunk optical cables or OC-3c transmit and receive optical cables from the NI-2 card of a subtending host chassis.
The bottom optical connector pair accommodates receive and transmit optical cables from the NI-2 card of a subtended node chassis that is configured for operation in an OC-3c network.

Both the SMF and MMF OC-3c/OC-3c NI-2 cards support the aggregation of up to 12 additional subtended Cisco 6015 chassis in a daisy chain configuration.

1.2.1.7 I/O Module Overview

The I/O module performs the following system tasks:

Provides the network WAN trunk physical interface
Provides the subtending physical interfaces to subtended node chassis

Figure 1-15 shows the location of the I/O module in the Cisco 6015 chassis.

Figure 1-15 I/O Module Location in the Cisco 6015 Chassis

2	I/O¹ module	6	xDSL line cards (slots 1 to 3)
3	DSL² interface module	7	Fan module
4	DC PEM³

1I/O = input/output

2DSL = digital subscriber line

3PEM = power entry module

Currently, there are two versions of the I/O module:

DS3+T1
E1

Note Use of the OC-3c/OC-3c NI-2 card in the Cisco 6015 disables whichever I/O module is installed in the chassis. However, an I/O module must be installed in the chassis for the system to operate correctly. The OC-3c/OC-3c NI-2 card does not support the DS3, E1, or T1 interfaces found on the front of the I/O modules. Therefore, the trunk and subtending interfaces are provided on the front of the OC-3c/OC-3c NI-2 card.

For hardware specifications for the I/O module, see the "I/O Module Specifications" section A-9.

The two versions of the I/O module are detailed in the following sections.

1.2.1.7.1 DS3+T1 I/O module

The DS3+T1 I/O module is used in North America. Figure 1-16 shows a close-up of the DS3+T1 I/O module faceplate.

The Cisco 6015 chassis follows the FCC part 68 industry standard convention for Tip and Ring connections on the twisted pairs of the 50-pin Champ connector. The Champ connectors are pinned out to accommodate quad-port or octal-port xTU-C line cards. If you are not currently using octal-port xTU-C line cards but plan to in the future, Cisco recommends that you use Champ cables that can accommodate higher density line cards.

Note See Table 2-6, "Tool and Equipment Requirements Checklist" for information on the types of cables needed.

See "Cable and Port Mapping Specifications" for port mapping tables.

1.2.1.9 DC PEM Overview

Each Cisco 6015 is equipped with a -48/-60V DC PEM, which distributes DC power within the chassis. Each DC PEM can be connected in one of the following ways:

To the fuse and alarm panel for DC power.
To the AC/DC converter, which is mounted below the Cisco 6015 chassis. The AC/DC converter converts AC power to usable DC power for the Cisco 6015.

Note The AC/DC converter can be used only in a commercial environment. It cannot be used in an outside-plant environment.

Note For hardware specifications for the DC PEM, see the "DC PEM Specifications" section A-10.

Figure 1-19 shows a close-up of the DC PEM faceplate.

1.2.3 AC/DC Converter

An optional AC/DC converter must be installed and connected to the DC PEM if the system is powered by AC power. The AC/DC converter converts 120/240V AC power to -48V DC power for the Cisco 6015 system. The AC/DC converter is orderable through Cisco.

Note The AC/DC converter can be used only in a commercial environment. It cannot be used in an outside-plant environment.

Figure 1-24 shows a close-up of the AC/DC converter faceplate.

Figure 1-24 AC/DC Converter Faceplate

1	2-pin connector	3	LEDs. When green, the left LED indicates that there is good AC input. When the right LED is green, it indicates that there is good DC output between the AC/DC converter and the DC PEM. If either LED is off, troubleshoot the AC/DC converter or the AC input.
2	Screw	4	AC power receptacle

Note An AC power cord applicable to your country's electrical specifications will accompany the AC/DC converter.

An AC/DC converter tray is available to house up to three AC/DC converters. The AC/DC converter tray is installed directly below the Cisco 6015 chassis. Extenders are available for the tray if you are installing the system in a 23-inch rack.

Note For hardware specifications for the AC/DC converter, see the "Cisco 6015 System Specifications" section on page A-2.

1.3 Management Software

You can provision and manage the Cisco 6015 system through the following management software:

Cisco IOS—A CLI that is available for network element provisioning.
CDM—A GUI designed to configure and manage the 6xxx series of Cisco IOS software-based DSLAMs. CDM provides the following areas of network management—fault, configuration, performance, and security. CDM runs with the Cisco EMF; both are installed on Sun workstations.

Note If your network contains multiple Sun workstations, you must dedicate one workstation as the server and all additional workstations as clients. The server should be the repository and distributor of database information from which the clients request information. The client workstations allow multiple users to monitor the managed network.

Note See the "Hardware Specifications" section on page A-1 for minimum software and network management release requirements per Cisco 6015 chassis component.

The supported alarms that are generated by the management software are

Critical visual—A critical visual alarm condition is indicated when the CRITICAL LED in the NI-2 card faceplate system alarm group lights. Whenever a critical alarm occurs

The critical visual alarm relay is activated.
Many or all subscribers that are connected to the node are affected (for example, failure of the network timing clock [NTC] or the trunk can cause a critical alarm).

Critical alarm indications are cleared when the alarm condition is resolved.

Major visual—A major visual alarm condition is indicated when the MAJOR LED in the NI-2 card faceplate system alarm group lights. Whenever a major alarm occurs

The major visual alarm relay is activated.
Several subscribers that are connected to the node are affected.

Major alarm indications are cleared when the alarm condition is resolved.

Minor visual—A minor visual alarm condition is indicated when the MINOR LED in the NI-2 card faceplate system alarm group lights. Whenever a minor alarm occurs

The minor visual alarm relay is activated.
A small number of subscribers that are connected to the node are affected.

Minor alarm indications are cleared when the alarm condition is resolved.

The facility alarm input, which is located on the rear of the chassis, allows an external event to trigger an alarm on the NI-2 card. (See the "Rear Interface Header" section for more information.)

Audible alarms can be turned off by pressing the ACO button.

For more information on alarms that are generated in the management software, see "Troubleshooting".
