PMC 1000 Series

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

1000 series WAN adapters comply with ATM Forum specification UNI 3.1 and TM 4.0. The cards 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 they manage and transmit raw cells, AAL1 and AAL2.

The PMC 1000-R is a 32-bit 33 MHz PMC adapter that provides a single full duplex ATM interface via a mated rear transition module (RTM) which defines the card's physical connector. The 1000-R uses the Conexant CN8236 SAR which interfaces with the RTM PHY via J3 on the backplane.

The 1000-R is supported by the PMC 1001-DE-RTM which is a rear transition module that provides a compatible interface for 45 Mb ATM DS3, 34 Mb ATM E3, and 6 Mb ATM J2 connections. The rear transition module employs the PMC-Sierra PM7347 PHY which provides a Utopia Level 2 bus. The PHY supports the 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. The PHY is also compatible with E3 transmission systems according to ETSI 300-269 and ETSI 300-270. The PHY supports direct cell mapping into DS3, E3 and J2 systems based on ITU-T G.804. It also provides a DS3/E3/J2 physical interface that features G.703-compliant dual BNC connectors.

The 1000-R is also supported by the PMC 1001-O3M-RTM and PMC 1001-O3S-RTM which provide compatible interfaces for multimode and single mode ATM OC3 connections. The ATM OC3 rear transition modules use the Conexant CX28250 PHY which provides the same features and performance characteristics as the front I/O version that is described next.

The PMC 1001-O3M and PMC 1001-O3S are 32-bit 33 MHz PMC adapters that provide a single full duplex 155 Mbps ATM OC3 port on the front panel. The cards employ the Conexant CN8236 SAR and the Conexant CX28250 PHY which are interconnected via the Utopia Level 2 bus. In 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. The physical interface is provided by SC connectors with options for single mode or multimode fiber optic cabling.

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

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.
