Hi we have a situation in which we need to be able to terminiate or bundle 8 T1 circuits on a 3845 router. What would be some recommendations? ie what type of cards would be needed, would those cards need to be have built in DSU's?? Any information would be appreciated.

Hi:

You can use an inverse mux with a HSSI serial interface for the 3845.

Thanks for the information, now looking at this for the prices.

If you are planning to go with built-in CSU/DSUs, you can purchase (4)VWIC2-2MFT-T1/E1 and if you are planning to go with external CSU/DSUs, then (2) HWIC-4T would do.

Per,

http://www.cisco.com/en/US/prod/collateral/routers/ps5855/product_data_sheet0900aecd8016a8e8.html

"Cisco 3845 integrated services router with two Gigabit Ethernet fixed LAN ports, one SFP slot, four NMEs, four HWICs, two AIM slots, 4 PVDM slots Cisco IP Base software, and AC power"

"Cisco 3800 Series routers also feature the widest range of voice-gateway interfaces, scaling to meet the needs of the smallest to largest branch requirements for voice termination densities using a combination of network modules, extension voice modules (EVMs), voice interface cards (VICs), voice/WAN interface cards (VWICs), and onboard packet voice DSP modules (PVDMs). Customers have unprecedented scalability for supporting up to 24 T1/E1 trunks and 88 foreign-exchange-station (FXS) ports for analog phones, fax machines, key systems, and conference stations."
