The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Premisys - Model: CPU-3 RCON - Condition: New From Surplus Stock - Price: Quote only - Availability: Not in Stock - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 5 lb - Shipping dimensions: 14x14x6 in ## Categories - Test Equipment > Telecom Test > Communications Equipment (primary) - Military and Embedded Equipment > Embedded & Industrial > Other Modular ## Details 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. ## Images -
