Chapter 1 Overview What is an Embedded MTA? What is an Embedded MTA? No matter how much of a cyberpro you are — or how much of a novice, there’s always something new to learn. The astute reader (you of course) may be wondering what an embedded MTA is.
Chapter 1 Overview The TA 102/202 eMTA at a Glance Built around the Terayon TJ 715x cable modem, the TA 102 (DOCSIS) and the TA 202 (Euro-DOCSIS) lets cable operators offer simultaneously to their subscribers, both high speed data and voice services. The TA 102 and TA 202 are two-line, PacketCable compliant eMTAs designed for indoor use.
Chapter 1 Overview Hardware Architecture Hardware Architecture In this section we delve into what’s inside the TA 102/202 eMTA. Figure 1-3 shows the basic architecture of the eMTA, and the following sections describe its I/O interfaces. 16 MB SDRAM CABLE MODEM CONTROL RF IN/OUT...
Hardware Architecture Chapter 1 Overview TA 102/202 eMTA Interfaces An eMTA must interact and communicate with its environment so it can perform useful tasks. It communicates with its environment through interfaces — electrical links that connect two or more pieces of equipment together. The TA 102/202 eMTA provides four interfaces for communicating with its environment.
Chapter 1 Overview Hardware Architecture High Speed Data Interfaces The TA 102/202 eMTA is versatile in that it offers two methods for connecting a subscriber PC to a CATV cable. There is a USB connection and an Ethernet connection. Only one connection (Ethernet or USB) is permitted. Ethernet Interface For an Ethernet connection, the point of connection between a subscriber PC and the TA 102/202 eMTA is the Ethernet Interface.
Hardware Architecture Chapter 1 Overview Additionally, both line interfaces support all telephony services, such as Caller ID, Call forwarding, Call Waiting, etc. For a European application, the POTS interface can func- tion with equipment compliant to the European Telecommunications Standards Insti- tute (ETSI) specification.
Chapter 1 Overview MIB Support The program that runs the DSP is called an audio codec. A codec (coined from coder/ decoder) is a pair of algorithms. One algorithm takes analog input and delivers digital output. The other algorithm does the opposite. NOTE NOTE: The PacketCable 1.0 Specification only supports audio codecs.
Security Chapter 1 Overview The TA 102/202 eMTA provides all of the following IETF IPCDN MIB features: • Cable Device MIB as per [RS99a] (or the RFC version when published). • Support for 32 concurrent filters in the Cable Device MIB without performance deg- radation.
Chapter 1 Overview Standards Compliancy PacketCable The TA 102/202 eMTA is fully compliant with the requirements described in the following PacketCable documents: • PKT-SP-CODEC-I05-040113 • PKT-SP-DQOS-I09-040402 • PKT-SP-EC-MGCP-I09-040113 • PKT-SP-MIB-MTA-I07-030728 • PKT-SP-MIB-SIG-I07-030728 • PKT-SP-MIBS-I07-030728 • PKT-SP-PROV-I09-040402 • PKT-SP-SEC-I10-040113.

Chapter 4 PacketCable Network Architecture If music, video and other multimedia content can be shot across HFC networks, why not conduct telephone conversations? With the PacketCable project from CableLabs conducting a phone conversation via an HFC network is now a real- ity.

Chapter 4 PacketCable Network Architecture PacketCable Network Architecture PacketCable Network Architecture What makes up a PacketCable Network you ask? At a very high level, a PacketCable network consists of three networks. Two of the networks are the familiar DOCSIS HFC Access Network and the Managed IP Network (headend).
PacketCable Functional Components Chapter 4 PacketCable Network Architecture The functional components of the HFC network include: a Cable Modem (CM), a Multi- media Terminal Adapter (MTA) or an eMTA (a cable modem with an embedded MTA) and a Cable Modem Termination System (CMTS). Referring again to Figure 4-1, the Managed IP Network provides the long-haul connec- tivity between other Managed IP and HFC Access Networks.
Chapter 4 PacketCable Network Architecture PacketCable Functional Components In the current release of PacketCable specifications, it is assumed the MTA is tightly coupled to a cable modem (CM). An MTA can be a standalone device or it can be embed- ded within the cable modem —...
PacketCable Functional Components Chapter 4 PacketCable Network Architecture The CMTS is also responsible for managing access network (cable modem network) resources for PacketCable services. Access network resources are first reserved when service is requested, then committed when service is delivered, and released when the service is complete.
Chapter 4 PacketCable Network Architecture PacketCable Functional Components Call Management Server (CMS) The CMS is a trusted network element that resides in the cable operator’s Managed IP Network. It is responsible for initiating, processing, and call forward signaling information. For example, when a subscriber places a call, the identity of the destination party (in the form of digits) is passed to the CMS.
PacketCable Functional Components Chapter 4 PacketCable Network Architecture Announcement Server (ANS) An Announcement Server is a network device that manages and plays informational tones in response to events that occur on the network. Announcement Server (ANS) Manages and plays informational tones and messages in response to events that occur on the network.
Chapter 4 PacketCable Network Architecture PacketCable Functional Components Associated hardware components include: • Provisioning servers • KDC servers for security • RKS servers for record keeping. Provisioning Servers Two kinds of provisioning occur in PacketCable, one on the IP side and one on the PacketCable side.
PacketCable Functional Components Chapter 4 PacketCable Network Architecture PSTN Gateway A PacketCable Network must be able to send calls to, and receive calls from the Public Switched Telephone Network (PSTN) — you know, the telephone company. But, because the PSTN is so much different than a PacketCable Network (its based on circuit- switched technology), the PacketCable Network must employ an interface device called a PSTN Gateway.
Chapter 4 PacketCable Network Architecture Placing a Call in a PacketCable Network Placing a Call in a PacketCable Network If you have read the “PacketCable Network Architecture” and “PacketCable Functional Components” sections, you have a pretty good understanding of the hardware and software applications involved in a PacketCable network.
