The Cisco AIR-LMC352 is proving hard to find.
Cisco End-Of-Lifed the Cisco AIR-LMC352 in January of 2006. Demand for the AIR-LMC352 Aironet 350 Series Client Adapter has been high over the last year. Large quantities of the AIR-LMC352 have been hard to find. You can still find them in small quantities on auctions sites like eBay.
The AIR-PCI352 (PCI card) has what appears to be an AIR-LMC352 included (installed). Many people have wondered if you can simply remove the AIR-LMC352 from the AIR-PCI352. The AIR-PCI352 is much more available and this would be a great solution for those of us looking for large quantities of AIR-LMC352s. The problem however is that although they look the same, they is a small but important difference.
The AIR-LMC352 adapter that is included on the AIR-PCI352 has a modified boot code that only allows it to work on the PCI card. If you attempt to remove that AIR-LMC352 and install it in a standard PCMCIA slot, the system will not recognize it. We have looked for ways to change the boot code (not the same as the flash software) but have not been successful.
If you are ever in the market for a Cisco AIR-LMC352, Teksavers in Austin, TX buys and sells new & used cisco AIR-LMC352 adapters and can save you up to 90% off list price. With their SAFE Guard program, you are assured of getting a used adapter in excellent working condition with a 1 year warranty included.Tags: air-lmc352 Thursday June 28, 2007 - 01:48pm (CDT) Permanent Link - What is a Cisco CISCO3725-DC-U?

What is a Cisco CISCO3725-DC-U?
The Cisco CISCO3725-DC-U is described by Cisco as "3725 router w/Universal Power Supply 24/48 volts 32F/256D". When compared with the CISCO3725 you can quickly see that the only difference appears to be the "Universal Power Supply 24/48 volts". The Flash and Memory are the same as a regular CISCO3725.
So what is this Universal Power Supply 24/48 volts? A quick search on Cisco's website reveals that the part number for this universal power supply is actually: PWR-3725-DC-U
The PWR-3725-DC-U is described as: "Spare Universal Power Supply 24 to 48 volts". The wiring requirements for this power supply are:A Cisco 3725 router with a DC-input power supply requires copper wire, size AWG 14 (1.625 mm2), for the power connections.
You can connect a single DC power source to either the A input or the B input. If there are parallel dual power sources, connect one source to the A input and one source to the B input; both sources must be the same polarity. A NEBS-compliant chassis ground connection is required with both single source and parallel dual sources
Key Note: The CISCO3725, including the CISCO3725-DC-U have been End-Of-Lifed by Cisco and have been replaced the by the CISCO3825 and CISCO3825-DC respectively.
If you are ever in the market for a Cisco CISCO3725 or CISCO3725-DC-U, Teksavers in Austin, TX buys and sells new & used cisco CISCO3725 routers and can save you up to 90% off list price. With their SAFE Guard program, you are assured of getting a used router in excellent working condition with a 1 year warranty included.Tags: cisco3725, cisco3725-dc-u Wednesday June 27, 2007 - 04:59pm (CDT) Permanent Link - What is the default memory on a Cisco AIM-CUE?

What is the default memory on a Cisco AIM-CUE?
The Cisco AIM-CUE is a module that physically integrates into a router chassis and offers industry-leading integrated messaging, voicemail, fax, automated attendant, optional interactive voice response (IVR), and a rich set of other messaging features.
The following routers support the AIM-CUE:
Cisco 2801, Cisco 2800 Series, Cisco 3700 Series, Cisco 3800 Series
The AIM-CUE originally shipped with 256MB of Flash Memory. It began shipping with 512MB Flash (Compact Flash) in March 2004. In December 2004, Cisco increased the default flash memory to 1GByte.
Key Note: Cisco Unity Express 1.1 and later (with voice mail message storage greater than 6 hours) exceeds the 512MB flash capacity and requires 1Gbyte. Customer should be aware of this requirement when purchasing the Cisco AIM-CUE.
If you are ever in the market for a Cisco AIM-CUE, Teksavers in Austin, TX buys and sells new & used cisco AIM-CUE modules and can save you up to 90% off list price. With their SAFE Guard program, you are assured of getting a used module in excellent working condition with a 1 year warranty included.

What is the difference? AIM-ATM AIM-ATM-VOICE-30 AIM-ATM-VOICE-30
The Cisco AIM-ATM, AIM-VOICE-30 and AIM-ATM-VOICE-30 are Voice/Fax and ATM AIM modules designed for the Cisco 2600, 2600XM, 2691, 3660 and 3700 series routers. These routers are equipped with an Advanced Integration Module (AIM) Slot.
AIM-ATM : Provides asynchronous transfer mode (ATM) WAN services.
AIM-VOICE-30 : Provides digital signal processor (DSP) services and can support up to 30 medium-complexity or 16 high-complexity voice channels.
AIM-ATM-VOICE-30 - Combines the features of the AIM-ATM and AIM-VOICE-30 modules onto a single AIM module.
The AIM-ATM offers ATM adaptation layer 2 (AAL2) and ATM adaptation layer 5 (AAL5) support for low-density T1/E1 data and voice connections over ATM networks.
The AIM-VOICE-30 contains DSPs that can support up to 30 voice channels when used with VWIC-MFT interface cards.
The AIM-ATM-VOICE-30 combines the ATM features of the AIM-ATM and voice features of the AIM-VOICE-30 in a single AIM module. The AIM-ATM-VOICE-30 also supports FR/HDLC/PPP ecapsulation and channelized voice on the same T1/E1 interface to PSTN.
Key Note: Before the introduction of the AIM-VOICE-30, providing digital voice service required the NM-HDV and analog voice services required the NM-1V/2V or NM-HDA. The AIM-VOICE-30, when used with a Voice/WAN interface card (VWIC-MFT), can provide digital voice service without using teh NM-HDV. This frees a valuable network module slot for other applications.
If you are ever in the market for a Cisco AIM-ATM, AIM-VOICE-30, or AIM-ATM-VOICE-30, Teksavers in Austin, TX buys and sells new & used cisco AIM-ATM, AIM-VOICE-30 and AIM-ATM-VOICE-30 modules and can save you up to 90% off list price. With their SAFE Guard program, you are assured of getting a used module in excellent working condition with a 1 year warranty included.

CISCO1751 replaces the award winning CISCO1750.
The Cisco 1750 has won many awards and has been the preferred router when converging voice and data networks for small businesses. The CISCO1751 expanded on the success of the CISCO1750 and taken the features to the next level. Features such as Voice, require additional available memory that only the CISCO1751 can provide. The CISCO1750 was end-of-lifed by Cisco on February 1, 2002. The replacement router was the CISCO1751. This article looks at both routers and explains the difference between the two.
Both the CISCO1750 and CISCO1751 include the following:
One autosensing 10/100 Fast Ethernet port
1 VIC Slot
2 WIC/VWIC Slots
One Console PortThe updated and newer CISCO1751 differs in the following:
Routing Performance: +40%
Base Memory (Flash/DRAM): 16MB/32MB (Compared to 4MB/16MB on CISCO1750)
Max Memory (Flash/DRAM): 16MB/96MB (Compared to 16MB/48MB on CISCO1750)
IEEE 802.1Q VLAN Routing: Yes
SPMM (DSP) Slots: 2 (Compared to 1 on CISCO1750)To summarize, the CISCO1751 offers higher performance, increased memory capacity for voice applications as compared to the CISCO1750.
If you are ever in the market for a Cisco CISCO1750 or CISCO1751, Teksavers in Austin, TX buys and sells new & used cisco CISCO1750 and CISCO1751 routers and can save you up to 90% off list price.
