Zhone Technologies / Premisys CPU-3 RCON CPU T1/E1 Module

Zhone Technologies / Premisys CPU-3 RCON CPU T1/E1 Module

This Zhone Technologies / Premisys CPU-3 RCON CPU T1/E1 Module is new from surplus stock.

Part Number: 880460

The CPU-3 RCON card supports two T1 or E1 WAN links in slot w1-1 and w1-2 with a redundant card (similarly configured) in slot w2. It supports another two T1 or E1 WAN link in slot w3-1 and w3-2 with a redundant card (similarly configured) in slot w4. If the T1/E1 link in w1-1 fails for any reason, the system will automatically switch to the similarly configured card in slot w2-1 (w1-2 would switch to w2-2 in the same way).

Slot w3 can support either a Single or a Dual T1/E1 WAN card. If the T1/E1 link in w3-1 fails for any reason, the system will automatically switch to the similary configured card in slot w4-1 (w3-2 would switch to w4-2 in the same way).

A system that uses an CPU-3 RCON card is said to operate in "enhanced bus-connect" mode. Two Models (CPU-3 RCON) can be installed in slots C1 and C2 to achieve CPU redundancy. The 8804 also supports 1x1 WAN redundancy.

  • Digital Cross-Connect
  • T1/E1 Conversion
  • Voice Compression
  • Optical HSU Interface to Protection Relays
  • Complete System Management
  • Powerful Diagnostic and Fault Isolation


The Zhone Technologies / Premisys IMACS - with over 50 optional service application modules, three flexible, scalable chassis options, and two firmware platforms - provides an almost limitless combination of services, applications and network interfaces.

The IMACS supports V.35, V.11/X.21, up to 8 HDSL, T1, E1, fractional T1, and fractional E1 interfaces. An integrated digital cross-connect is available to consolidate multiple voice, data, and T1/E1 services. Three chassis models, IMACS 600, 800, and 900, differ in their card capacity and card install options (front, or front and rear). All models support the same range of modular cards, power supplies, and system redundancy options. All IMACS systems can be fully managed either with local craft interface through a VT100, PC, or through the OnLine Element Management System using standard SNMP interfaces.

In addition, IMACS offers a powerful array of integrated network diagnostic and fault isolation capabilities. These include Bit Error Rate Testers, test tone and signaling state generation, digital and analog loopback support, and remote configuration and control. IMACS meets stringent standards criteria, such as NEBS and CE, which means the user can deploy the IMACS almost anywhere in the user's network.

The IMACS is designed to continuously meet the needs of a changing telecommunications landscape. With its advanced patented modular architecture, voice and data services can be deployed quickly and cost effectively. Applications include: POTS (FXS, FXO, E and M), ISDN (BRI and PRI), voice compression (ADPCM and ACELP), VPN access, Internet access, integrated routing capabilities, voice over Frame Relay, Digital Data Networks (DDN), analog private lines, and numerous others. And the IMACS is being used in both public and private, as well as traditional facilities-based and wireless networks.
