SIST EN 302 878-1 V1.1.1:2012 is the Slovenian adoption of ETSI EN 302 878-1 V1.1.1, published by SIST. It is the general part of the DOCSIS 3.0 series for third generation transmission systems for interactive cable television services, and it explains the system context, terminology, and document structure for cable modems and cable modem termination systems. It is aimed at engineers, operators, and vendors who need to see how the DOCSIS 3.0 parts fit together before working on detailed interface or security requirements.

What does SIST EN 302 878-1 V1.1.1:2012 specify?

SIST EN 302 878-1 V1.1.1:2012 specifies the general framework for the DOCSIS 3.0 family. It sets the scope, background assumptions, compatibility model, definitions, and the way the five-part deliverable is organized.

Part	What it covers
Part 1	General; DOCSIS 3.0
Part 2	Physical Layer; DOCSIS 3.0
Part 3	Downstream Radio Frequency Interface; DOCSIS 3.0
Part 4	MAC and Upper Layer Protocols; DOCSIS 3.0
Part 5	Security Services; DOCSIS 3.0

Clause 1 describes the two technology options and the cable-network background used by the series. Clause 2 lists the references needed to apply the standard. Clause 3 gives the key definitions and abbreviations, and Clause 4 explains what each part of the multi-part deliverable covers.

What are the key requirements of SIST EN 302 878-1 V1.1.1:2012?

SIST EN 302 878-1 V1.1.1:2012 does not define detailed PHY or MAC parameters itself. Its main technical value is in setting the operating model that the other parts build on.

• Clause 1.1 gives two technology options with equal priority. Compliance means using one option or the other, not both, and the two options are not required to interoperate. In practice, buyers and integrators must choose the option that matches the deployment region and channel plan.
• Clause 1.2 assumes a coaxial-based broadband access network, either all-coax or Hybrid Fibre/Coaxial [HFC], with two-way transmission and tree-and-branch architecture. It also discusses long network distances and propagation delay. In practice, this frames the timing and reach that equipment must tolerate.
• Clause 1.2.2 describes the DOCSIS network around the Cable Modem [CM], Cable Modem Termination System [CMTS], home network, and back-office systems. In practice, a CM bridges the customer side and the cable network, while a CMTS forwards traffic between the cable plant and the operator network.
• Clause 1.2.2.1 names the support systems used in deployment: DHCP for boot configuration, configuration file servers, software download servers, Time Protocol servers, certificate revocation services, SNMP managers, syslog servers, and IPDR collectors. In practice, this tells operators what service systems they need around the DOCSIS network.
• Clause 1.2.3 states the service goals: more channel capacity, stronger network security, wider addressability, and support for new service offerings. It also describes transparent bi-directional Internet Protocol [IP] traffic over the cable network. In practice, this is the business and network purpose behind DOCSIS 3.0.
• Clause 1.2.4 states that DOCSIS 3.0 is backward-compatible with DOCSIS 2.0, 1.1, and 1.0 equipment. In practice, mixed fleets can be planned around the compatibility rules, and Part 5 is used for BPI/BPI+ compatibility details.
• Clause 4 explains the role of Parts 2 to 5. In practice, Part 1 is the map to the detailed technical documents.

What terms does SIST EN 302 878-1 V1.1.1:2012 define?

SIST EN 302 878-1 V1.1.1:2012 defines the terms and abbreviations needed to read the series consistently.

• DOCSIS [Data-Over-Cable Service Interface Specifications] - the cable data-service family that this series specifies.
• CM [Cable Modem] - the layer two termination device at the network end of a third generation DOCSIS system.
• CMTS [Cable Modem Termination System] - the operator-side system that connects the cable network to the back-office network.
• CPE [Customer Premises Equipment] - customer devices connected behind the cable modem, such as routers or PCs.
• HFC [Hybrid Fibre/Coaxial] - a network that combines fibre and coaxial cable.
• BPI+ [Baseline Privacy Interface Plus] - the DOCSIS security architecture for authentication and encrypted sessions.
• EAE [Early Authentication and Encryption] - the use of BPI+ earlier in provisioning.
• SSD [Secure Software Download] - the protected software-loading process for the cable modem.

Who uses SIST EN 302 878-1 V1.1.1:2012?

SIST EN 302 878-1 V1.1.1:2012 is used by cable operators, equipment vendors, and integrators working on DOCSIS 3.0 systems. It is also relevant to provisioning, network management, and security teams because it names the support systems and companion parts that govern a deployment.

What changed in SIST EN 302 878-1 V1.1.1:2012 from the previous edition?

SIST EN 302 878-1 V1.1.1:2012 incorporates engineering changes and updates TS 102 639-1. The publication history shows it as version V1.1.1.

Which standards are used with SIST EN 302 878-1 V1.1.1:2012?

SIST EN 302 878-1 V1.1.1:2012 is applied together with these normative references:

Standard	What it contributes
EN 302 878-2	Physical Layer requirements for DOCSIS 3.0 CMs and CMTSs
EN 302 878-3	Downstream Radio Frequency Interface requirements
EN 302 878-4	MAC and Upper Layer Protocols, including channel bonding, multicast, and IPv6
EN 302 878-5	Security Services, including BPI+, EAE, and SSD

What does the SIST EN 302 878-1 V1.1.1:2012 document contain?

SIST EN 302 878-1 V1.1.1:2012 contains the Intellectual Property Rights notice, Foreword, Scope, References, Definitions and abbreviations, and an overview of the multi-part deliverable. The foreword includes a table linking the ETSI parts to CableLabs DOCSIS and SCTE standards, and the body uses figures to show the DOCSIS network, transparent IP traffic, and the reference architecture. The document also records its publication history.

5 Draft ETSI EN 302 878-1 V1.1.0 (2011-04)
1 Scope
The present document is part 1 of a multi-part series of specifications that define the third generation of high-speed
data-over-cable systems. This series was developed for the benefit of the cable industry, and includes contributions by
operators and vendors from North America, Europe, and other regions. All documents in this series are required to
implement the third-generation transmission system for interactive cable television services.
1.1 Technology Options
This multi-part deliverable includes two technology options that have equal priority and are not required to be
interoperable. One technology option is based on the downstream multi-program television distribution that is deployed
in North America using 6 MHz channelling. The other technology option is based on the corresponding European
multi-program television distribution. Both options have the same status. Compliance with the present document
requires compliance with the one or the other of these implementations, not with both. It is not required that equipment
built to one option shall interoperate with equipment built to the other.
These technology options allow operators flexibility in mandated areas of operation, including any frequency planning,
EMC (electromagnetic compatibility), and safety requirements. For instance, the 6 MHz downstream based option
defined in EN 302 878-2 [1] might be deployable within an 8 MHz channel plan.
Backwards compatibility with earlier versions of that technology is only ensured within the same technology options
referred to above and not between the two options.
1.2 Background
1.2.1 Broadband Access Network
A coaxial-based broadband access network is assumed. This may take the form of either an all-coax or hybrid-
fibre/coax network. The generic term "cable network" is used here to cover all cases.
A cable network uses a tree-and-branch architecture with analog transmission. The key functional characteristics
assumed in the present document are the following:
• Two-way transmission.
• A maximum optical/electrical spacing between the CMTS and the most distant CM of 100 miles (160 km) in
each direction, although typical maximum separation may be 10 miles to 15 miles (16 km to 24 km).
• A maximum differential optical/electrical spacing between the CMTS and the closest and most distant
modems of 100 miles (160 km) in each direction, although this would typically be limited to 15 miles (24 km).
At a propagation velocity in fibre of approximately 1,5 ns/ft (5 ns/m), 100 miles (160 km) of fibre in each direction
results in a round-trip delay of approximately 1,6 ms.

Foreword
This European Standard (EN) has been produced by ETSI Technical Committee Access, Terminals, Transmission and
Multiplexing (ATTM).
The present document is part 1 of a multi-part deliverable covering the Third Generation Transmission Systems for
Interactive Cable Television Services - IP Cable Modems, as identified below:
Part 1: "General; DOCSIS 3.0";
Part 2: "Physical Layer; DOCSIS 3.0";
Part 3: "Downstream Radio Frequency Interface; DOCSIS 3.0";
Part 4: "MAC and Upper Layer Protocols; DOCSIS 3.0";
Part 5: "Security Services; DOCSIS 3.0".
This multi-part deliverable is based on the CableLabs DOCSIS set of specifications which are also standardized in the
United States by SCTE. Table 1 indicates for the specifications in this series the equivalent CableLabs DOCSIS
specifications and SCTE Standards.

1 Scope
The present document is part 1 of a multi-part series of specifications that define the third generation of high-speed
data-over-cable systems. This series was developed for the benefit of the cable industry, and includes contributions by
operators and vendors from North America, Europe, and other regions. All documents in this series are required to
implement the third-generation transmission system for interactive cable television services.
1.1 Technology Options
This multi-part deliverable includes two technology options that have equal priority and are not required to be
interoperable. One technology option is based on the downstream multi-program television distribution that is deployed
in North America using 6 MHz channelling. The other technology option is based on the corresponding European
multi-program television distribution. Both options have the same status. Compliance with the present document
requires compliance with the one or the other of these implementations, not with both. It is not required that equipment
built to one option will interoperate with equipment built to the other.
These technology options allow operators flexibility in mandated areas of operation, including any frequency planning,
EMC (electromagnetic compatibility), and safety requirements. For instance, the 6 MHz downstream based option
defined in EN 302 878-2 [1] might be deployable within an 8 MHz channel plan.
Backwards compatibility with earlier versions of that technology is only ensured within the same technology options
referred to above and not between the two options.
1.2 Background
1.2.1 Broadband Access Network
A coaxial-based broadband access network is assumed. This may take the form of either an all-coax or Hybrid
Fibre/Coaxial network. The generic term "cable network" is used here to cover all cases.
A cable network uses a tree-and-branch architecture with analog transmission. The key functional characteristics
assumed in the present document are the following:
• Two-way transmission.
• A maximum optical/electrical spacing between the CMTS and the most distant CM of 100 miles (160 km) in
each direction, although typical maximum separation may be 10 miles to 15 miles (16 km to 24 km).
• A maximum differential optical/electrical spacing between the CMTS and the closest and most distant
modems of 100 miles (160 km) in each direction, although this would typically be limited to 15 miles (24 km).
At a propagation velocity in fibre of approximately 1,5 ns/ft (5 ns/m), 100 miles (160 km) of fibre in each direction
results in a round-trip delay of approximately 1,6 ms.
