Overview of Cisco Universal Broadband Routers

The Cisco uBR7100 series and Cisco uBR7200 series universal broadband routers are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards and designed to be installed at small cable operators and multiple dwelling unit (MDU) operators to enable them to offer services such as e-mail, high-speed Internet access, voice, and digital video over a bidirectional cable television and IP backbone network. The universal broadband routers function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR905, Cisco uBR924, and Cisco uBR925 cable access routers, and other DOCSIS-compliant cable modems (CMs) and set-top boxes (STBs).

Both the Cisco uBR7100 series and Cisco uBR7200 series universal broadband routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid fiber-coaxial (HFC) network. For cable plants not fully upgraded to support two-way cable transmission, the routers support DOCSIS-compliant telco return, where the cable modem's return path to the CMTS is via a dial-up telephone line connection instead of an upstream channel over the coaxial cable. The telco-return delivery mechanism enables cable operators to accelerate deployment of high-speed data services before the cable systems are upgraded to two-way plants.

Cisco uBR7100 Series Universal Broadband Routers

The Cisco uBR7100 series routers provide a fixed set of WAN and LAN interfaces with a combination of fixed and modular interfaces, allowing both flexibility and simplicity in configuration. Each Cisco uBR7100 series router includes one modular single-width port adapter, one integrated cable interface with an internal upconverter, and two integrated Fast Ethernet ports. The cable interface is based on the Cisco uBR-MC14C cable interface line card and is not field-replaceable.

The Cisco uBR7100 series routers support IP routing through the following optional WAN and LAN port adapters: Ethernet, Fast Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3c, and Asynchronous Transfer Mode (ATM) media. For more information, see Table 4.

Depending on the model, the Cisco uBR7100 series routers support the following two standards:

•Data Over Cable Service Interface Specifications (DOCSIS), which supports the 6 MHz North American channel plans using the ITU J.83 Annex B RF standard. The downstream uses a 6 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports the 5 to 42 MHz frequency range.

•European Data Over Cable Service Interface Specifications (EuroDOCSIS), which supports the 8 MHz Phase Alternating Line (PAL) and Systeme Electronique Couleur Avec Memoire (SECAM) channel plans using the ITU J.112 Annex A RF standard. The downstream uses an 8 MHz channel width in the 85 to 860 MHz frequency range, and the upstream supports multiple channel widths in the 5 to 65 MHz frequency range.

The Cisco uBR7100 series offers the following models:

•The Cisco uBR7111 and Cisco uBR7111E universal broadband routers provide a cable interface with one downstream port and one upstream port. The downstream port can be output either as an RF signal through the integrated upconverter or as an IF signal for processing by an external upconverter. The Cisco uBR7111 router supports DOCSIS cable plants, and the Cisco uBR7111E supports EuroDOCSIS cable plants.

•The Cisco uBR7114 and Cisco uBR7114E universal broadband routers provide a cable interface with one downstream port and four upstream ports. The downstream port can be output either as an RF signal through the integrated upconverter or as an IF signal for processing by an external upconverter. The Cisco uBR7114 router supports DOCSIS cable plants, and the Cisco uBR7114E supports EuroDOCSIS cable plants.

---

Note All images support all of the hardware listed in the "Supported Hardware" section, unless otherwise indicated.

---

System Interoperability

This section clarifies the operation of certain features in the Cisco uBR7100 series universal broadband routers.

•DOCSIS 1.0 Baseline Privacy

DOCSIS baseline privacy interface (BPI) gives subscribers data privacy across the RF network, encrypting traffic flows between the CMTS and CM. BPI ensures that a CM, uniquely identified by its Media Access Control (MAC) address, can obtain keying material for only those services to which it has authorized access.

To enable BPI, choose software at both the CMTS and CM that support the mode of operation. For the Cisco uBR7100 series software, choose an image with "k1" in its file name or BPI in the feature set description.

The CM must also support BPI. CMs must have factory-installed RSA private/public key pairs to support internal algorithms to generate key pairs prior to first BPI establishment. BPI must be enabled using the DOCSIS configuration file.

---

Note RSA stands for Rivest, Shamir, and Adelman, inventors of a public-key cryptographic system.

---

•CM Interoperability

The Cisco uBR7100 series interoperates with the following cable modems:

–DOCSIS-based (Cisco uBR7111 and Cisco uBR7114) or Euro-DOCSIS (Cisco uBR7111E and Cisco uBR7114E) two-way CMs that support basic Internet access, VoIP, or Virtual Private Networks (VPNs).

–Telco-return CMs—To support telco return, use a Cisco uBR7100 series software image that contains "t" in its file name. The telco-return CM must be DOCSIS-based or compliant and must be configured to support telco return.

---

Note Some third-party telco-return CMs cannot receive traffic over the same downstream channel as CMs operating on a two-way data system. In these instances, segment your cable plant to allow more than one downstream channel.

---

•DOCSIS 1.0 Extensions

The Cisco uBR7100 series supports the following DOCSIS 1.0 quality of service (QoS) extensions:

–Multi-Service ID (SID) support, allowing the definition of multiple SIDs on the upstream—Voice traffic can be designated on a higher QoS committed information rate (CIR) secondary SID, while data traffic can be forwarded on a best-effort basis on a primary SID. Secondary SIDs are higher QoS CIR-type classes that have a nonzero minimum reserved rate (CIR-type service). These SIDs receive preferential treatment at the CMTS for grants over any tiered best-effort type data SID of that upstream. Reliable operation with voice requires multiple SIDs—at least two per CM to separate voice from data. In DOCSIS 1.0, SIDs are set up statically. When supporting DOCSIS 1.0 extensions, SIDs can be set up statically or dynamically. Both the CMTS and CM must support this capability.

–CM-initiated dynamic MAC messages—Dynamic Service Addition (DSA) and Dynamic Service Deletion (DSD). These messages allow dynamic SIDs to be created and deleted at run-time on a per-VoIP call basis.

–Unsolicited grant service (constant bit rate [CBR] scheduling) on the upstream—This helps provide a higher-quality channel for upstream VoIP packets from an Integrated Telephony Cable Modem (ITCM) such as the Cisco uBR924 cable access router.

–Ability to provide separate downstream rates for any given ITCM, based on the IP-precedence value in the packet—This helps separate voice signaling and data traffic that goes to the same ITCM to address rate-shaping purposes.

–Concatenation—To increase the per-CM upstream throughput in certain releases of software, Cisco uBR7100 series software supports a concatenated burst of multiple MAC frames from a CM that supports concatenation.

---

Note All DOCSIS 1.0 extensions are activated only when a CM or Cisco uBR924 that supports these extensions solicits services via dynamic MAC messages or the feature set. If the CMs in your network are pure DOCSIS 1.0-based, they will receive regular DOCSIS 1.0 treatment from the CMTS.
