{{>toc}} h1. Cisco AS5400 This is a modular access server for voice, data (ISDN) and modem calls. It has a modular archticture and there are a variety of suitable modules. The System consists of PSU, a Mainboard, a backplane and three trays. Each of the three Trays can house two modules. The mainboard also directly houses one module. * attachment:Cisco_AS5350_AS5400_Software_Configuration_Guide.pdf h2. Mainboard * 2x Gigabit Ethernet: Broadcom BCM5481 * 1x coaxial BITS (timing): Dallas DS2 * 1x Marvell GT-96124-B-2 F55551.0 * Altera Cyclone EP1C4F400C8 * Xilinx Spartan XC2S300E * PI7C8150 PCI bridge (module to backplane) * PI7C8150 PCI bridge (CPU to backplane) * PI7C8150 PCI bridge (unused PCI slot) * 1x unknown under natural color heatsink * 1x unknown under black anodized heatsink (700-09863-01 REV A0 / VETTE 0824) * CompactFlash slot with 128MB CF card * Memory slot holding STEC STM122116RT 512MB 2R8 PC2700E CL2.5-3-3 RAM {{thumbnail(20231008_140054.jpg)}} {{thumbnail(20231008_140130.jpg)}} {{thumbnail(20231008_140205.jpg)}} {{thumbnail(20231008_140234.jpg)}} {{thumbnail(20231008_140148.jpg)}} {{thumbnail(20231008_140130.jpg)}} {{thumbnail(20231008_140113.jpg)}} h2. Trays (73-9527-01) The tray has one connection to the backplane, and two proprietary high-density connectors for the two modules. The central TDM component on the Tray is the Zarlink *MT90866* _2432x2432 non-blocking digital switch with H.110 interface_ (data sheet see attachment:MT90866.pdf. Each module's PCI bus is bridged to the backplane PCI using a Pericum *PI7C8150* _2-port PCI-to-PCI Bridge_ (data sheet see attachment:PI7C8150.pdf) {{thumbnail(20231008_140440.jpg)}} {{thumbnail(20231008_140358.jpg)}} {{thumbnail(20231008_140330.jpg)}} {{thumbnail(20231008_140311.jpg)}} h2. Modem modules h3. NP108 module (800-0828-01) This module is built around 18x Conexant/Mindspeed *RL56CSMV/6* chips (data sheet see attachment:RL56CSMV_6.pdf). Each of the chips features its own *MT48LC4M16A2* RAM chip. Internally, each of those chips contains an _ARM core_ for management, and six _Digital Data Pump_ dies. Interfacing with the backplane is done via 3x Intel i960. {{thumbnail(20231008_111332.jpg)}} {{thumbnail(20231008_111347.jpg)}} {{thumbnail(20231008_111332.jpg)}} {{thumbnail(20231008_125506.jpg)}} {{thumbnail(20231008_125448.jpg)}} {{thumbnail(20231008_123445.jpg)}} {{thumbnail(20231008_123504.jpg)}} h3. NP60 module (800-05643-01) This module is the little brother of the NP108. It is built around 10x Conexant/Mindspeed *RL56CSMV/6* chips (data sheet see attachment:RL56CSMV_6.pdf). Each of the chips features its own *MT48LC4M16A2* RAM chip. Internally, each of those chips contains an _ARM core_ for management, and six _Digital Data Pump_ dies. Interfacing with the backplane is done via 2x Intel i960. {{thumbnail(20231008_125215.jpg)}} {{thumbnail(20231008_130813.jpg)}} {{thumbnail(20231008_130827.jpg)}} {{thumbnail(20231008_130846.jpg)}} {{thumbnail(20231008_130859.jpg)}} h3. PSU (Power Supply Unit) As can be seen on the pictures, the PSU is a single unit that houses two redundant circuit board assmeblies, each with its own AC input. {{thumbnail(20231008_140503.jpg)}} {{thumbnail(20231008_140021.jpg)}} {{thumbnail(20220422_162511.jpg)}} {{thumbnail(20220422_162507.jpg)}} {{thumbnail(20220422_162503.jpg)}} {{thumbnail(20220422_162503.jpg)}} {{thumbnail(20220422_162501.jpg)}} h2. Trunk interface modules h3. 8PRI (800-06543-01) This is an 8x PRI (E1/T1) interface. Each PRI interface has its own EMI / overvoltage / transforer section, followed by a Mindspeed *Bt8370KPF* E1/Ta transceiver (datasheet see attachment:Bt8370KPF.pdf). The main CPU is an MPC860 PowerPC, interfaced via a PLX *PCI9054* PCI bridge (datasheet see attachment:PCI9054.pdf). There are also two PMC FREEDM8 *PM7366* _Eight Channel Frame Engine and Datalink Manager_ (datasheet see attachment:PM7366.pdf). {{thumbnail(20231008_125417.jpg)}} {{thumbnail(20231008_125359.jpg)}} {{thumbnail(20231008_125347.jpg)}} {{thumbnail(20231008_125335.jpg)}} {{thumbnail(20231008_125312.jpg)}} {{thumbnail(20231008_125249.jpg)}} {{thumbnail(20231008_125229.jpg)}}
