The PCI 1000 series consists of WAN adapters that can be used in routers or other products running Linux. The 1000 series includes high-performance ATM adapters with one DS3/E3/J2, OC3, or OC12 interface.

1000 series cards comply with ATM Forum specification UNI 3.1 and TM 4.0. The adapters are based on advanced ATM segmentation and reassembly controllers (SARs) that are designed to optimize PCI bus utilization for increased performance with small packets. 1000 series adapters segment and reassemble AAL0, AAL3/4 and AAL5, and the cards manage and transmit raw cells, AAL1 and AAL2.

The PCI 1001-DE is a 32-bit 33 MHz PCI adapter that provides a full duplex software configurable interface for 45 Mb ATM DS3, 34 Mb ATM E3, and 6 Mb ATM J2 connections. The card uses the Conexant CN8236 SAR and the PMC-Sierra PM7347 PHY which are connected via a Utopia Level 2 bus. The PHY supports Physical Layer Convergence Protocol (PLCP) which is compatible with DS3 transmission systems according to the ATM Forum UNI specification, ANSI TA-TSY-000773, and ANSI TA-TSY-000772, and with E3 transmission systems according to ETSI 300-269 and ETSI 300-270. The PHY also supports direct cell mapping into DS3, E3, and J2 systems based on ITU-T G.804. The DS3/E3/J2 physical interface features G.703 compliant dual BNC connectors.

The PCI 1001-O3M and PCI 1001-O3S are 32-bit 33 MHz PCI adapters that provide a full duplex 155 Mbps ATM OC3 port. The cards employ the Conexant CN8236 SAR and the Conexant CX28250 PHY which are connected by a Utopia Level 2 bus. In the half duplex mode, the cards support burst rates up to 200 Mbps. The front end supports SONET STS-3c or SDH STM-1 with built-in performance and alarm monitoring. Physical interface is provided by SC connectors with options for single mode or multimode fiber optics.

The PCI 1001-O12S is a 32/64-bit 33/66 MHz ATM adapter that provides a full duplex 622 Mbps ATM OC12 port. The card employs the Conexant CN8237 SAR and the PMC-Sierra PM5356 PHY which are connected together via a Utopia Level 2 bus. The PHY supports SONET STS-12c or SDH STM-4, and the physical interface provides an SC connector that supports single mode fiber optics.

The traffic management co-processor in each SAR supports Constant Bit Rate (CBR), Variable Bit Rate (VBR), Unspecified Bit Rate (UBR), Available Bit Rate (ABR), Guaranteed Frame Rate (GFR) and Generic Flow Control (GFC). In order to maximize line utilization, the xBR traffic management block automatically schedules each virtual channel connection (VCC) according to user assigned parameters.
