DUAL E3-2 INTERFACE CARD E119.0 This card supports two E-3 (34Mb/s) interfaces. Must be mounted in a High Speed Peripheral Shelf-2 (90-0652-02). It may be configured in non-redundant and redundant configurations (ie. with another card). Provides electrical (metallic) E-3 interfaces. Requires a 3600 Switching Shelf Generic C119.0. Compatible with older generation DE3 cards (90-1224-xx).

DUAL MAU This Dual MAU provides redundancy connectivity between adjacent pairs of redundant Call Processing cards. This Dual MAU is mandatory if Call Processing 1+1 hot redundancy is to be used on the Call Processing cards, available in R4.0 and later. The Dual MAU is not required (for either warm or hot redundancy) with the Integrated CallP/PNNI system configuration. The IP Services Card (ISC - 90-6184-xx) uses the same Dual MAU. The Dual MAU is mandatory to interconnect two adjacent ISC's running in 1+1 Redundancy mode, available in R4.2 and later. If the MAU is missing, the working card becomes active and the secondary ISC card is neither active nor providing redundancy.

The Dual MAU is mandatory to interconnect two adjacent ISC's running in 1+1 Redundancy mode. If the MAU is missing, the working card becomes active and the secondary ISC card is neither active nor providing redundancy. This Dual MAU is also used for redundant call processing cards on systems running non-integrated control software.

DUAL SHELF CABLE 4FT This cable assembly is required when configuring redundant Switching Shelves. Included is one cable assembly (4 ft).

DUAL SHELF CABLE 8UCS This assembly includes all the components required to interconnect two 8 UCS Single Shelves (90-0010-04/05/07/10) in a redundant capacity (i.e. two sets of Upper and Lower Balance Transceiver cards and four intershelf cables). This assembly can also be used for 6 UCS Single Shelf applications when the Dual Shelf Cable Assy Adaptor (90-1064-01) is also used. The 90-0090- 02 assembly can be used in non-redundant 8 UCS applications or as replacement parts for the 90-0090-05 assembly.

Dual Speed 100Base-FX or 1000Base-X Ethernet optical transceiver (SFP MSA). Supports multimode fiber over 1310nm wavelength (nominal) with an LC connector. Typical reach of 550m at Gigabit speed and 2km at 100Mbit speed. Note: - at 100Mbit speed, this SFP can interoperate with SFP-100-LC-MM or similar transceiver on the other end,- at Gigabit speed, this SFP cannot interoperate with SFP-GIG-SX or similar transceiver on the other end running over 850nm wavelength.

Dual Speed 100Base-FX or 1000Base-X Ethernet optical transceiver (SFP MSA). Supports single mode fiber over 1310nm wavelength (nominal) with an LC connector. Typical reach of 10km at Gigabit speed and 100Mbit speed.Note: - at 100Mbit speed, this SFP can interoperate with SFP-100-LC-SM15 or similar transceiver,- at Gigabit speed, this SFP can interoperate with SFP-GIG-LX or similar transceiver.

DUAL T1 1.544 MBPS CARD clei This card provides two 1.544 Mbps T1 digital trunk interfaces. Used to compress 44 voice channels to a single T1 link when equipped with the Voice Compression Module (90-0566-01). Requires one T1 LIM (90-0567-01) for each T1 interface connection to a T1 channel service unit. Also supports one CSU-2 Module (90-0161-02) for each T1 interface connection directly to a carrier's T-1 lines when using Generic 1115 or greater. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.
