OVERVIEW
Freescale Semiconductor, Inc.
BENEFITS
Provides intelligence smart development remote access server platforms Delivers cutting edge features designed specifically communications tasks
remote access server enables users local network access, retrieve, file, print services though they were. example, people telecommuting office from home dial into remote access server. Through that server, users access drives printers office though they were connected internal office LAN. Security paramount consideration remote access applications.

DESIGN CHALLENGES
Figure illustrates remote access server that handles multiple traffic types: Point-to-point protocol (PPP) serial link Internet protocol (SLIP) over analog modems long-distance access other protocols broadband traffic Routing functionality such traffic; e.g., using Asynchronous types terminal services such Telnet TN3270 Virtual private network (VPN) (Internet Protocol Security, IPSec) tunnel termination Often, translation between different protocols must provided. combination interfaces services presents difficult challenge server implementation, especially light time-to-market constraints. Traditional approaches required separate hardware general-purpose CPUs each interface type protocol, resulting many individual designs, along with limited reuse software.

MOTOROLA SOLUTION
Motorola's comprehensive communications networking processor portfolio provides intelligence smart development remote access server platforms. Motorola's processor portfolio delivers cutting edge features designed specifically communications tasks.
Approach
Motorola's PowerQUICCfamily integrated communications processors enables approach design challenges, that delivers this broad solution within single hardware architecture. family's dual-core architecture allows dedicated RISC communications processor on-board memory enable single PowerQUICC-based interface built with variety different interface types order create common platform. Protocol software implemented within PowerQUICC processor, while core, which compliant with PowerPCarchitecture, handles control/management plane functions. members Motorola's leading PowerQUICC family integrated communications processors easily upgradable through downloadable microcode packages. These innovative microcode packages provide ideal control data plane functionality, further enabling customers speed time-to-market focus value-added product elements. Figure depicts design that uses Motorola's MPC8260 PowerQUICC integrated communications processor remote server control configuration: DSPs analog modem traffic reside local bus; data transferred from bank using flexible IDMA engine. Depending needs office LAN, MPC8260 capable Mbps Aover Universal Test Operations Interface A(UTOPIA), 10/100 Base-T Ethernet, clear-channel high level data link control (HDLC) transparent time division multiplex (TDM) channels supported. Slower operation, administration, maintenance (OAM) messaging other areas server system accomplished using variety on-chip peripheral interfaces serial channels. full rate OC-3 (IPSec) support through MPC185 security processor.
