2 /T1 or /T1 Access Unit with Integrated Router DESCRIPTION is an /T1 or fractional /T1 integrated access device (IAD), which enables service providers to bundle data, voice and IP access services over a single or T1 access line (see Figure 1). is also ideal for management applications in cellular or SDH environments (see Figure 2 and Figure 3). Supported WAN services are: T1 or fractional T1 CSU/DSU operating at up to Mbps or fractional, with or without LTU, operating at up to Mbps over 2-wire SHDSL link or T1 over fiber optic links Frame Relay with auto-learn of DLCI and maintenance protocol ISDN BRI ( U or S interface) for data services backup. APPLICATIONS An integrated router supports IP/IPX routing and transparent bridging. An optional internal 4-port Ethernet/Fast Ethernet switch can be installed in place of LAN ports. Internet access capabilities are enhanced through: IP Service Access authentication that is provided by PAP/CHAP Solid Firewall that protects an office LAN from undesired entry from the Internet NAT that allows the sharing of several legal IP addresses between the various LAN users Single IP address translation feature that allows a small or medium office LAN to connect to the Internet using a single dynamically or statically allocated IP address DHCP server that allows the sharing of ISP address pools between DHCP clients on the LAN. The sub-/t1 or quad analog voice drop & insert ports provide toll-quality voice transmission. The fail-safe bypass of the sub-/t1 link ensures the continuity of voice services in case of power supply failures. ISDN or dial backup ensure the continuity of data services. An optional data port can be utilized either as a second serial router port or as a transparent N 64, N 56 data port for legacy equipment connectivity. Configuration is easily accomplished through a quick setup menu using a terminal attached to the control port or by Telnet access into the device over the LAN/WAN.

3 features a variety of inband and out-of-band management options. These options include dedicated timeslot, dedicated DLCI and dial-in connectivity. The SNMP agent provides management by RADview or any other standard SNMP management station. Undesired access to via Telnet or SNMP can be blocked or password protected. The dual-level management authentication allows the user access to router configuration parameters, while restricting the user access to network configuration parameters. Software download is available via the control port using XMODEM and via LAN/WAN using TFTP. Parameter file download and upload is available via LAN or WAN using TFTP.
