I like to go cheap on the frame switch. I use a 2522 router. It has plenty
of serial interfaces although all but two will only support up to 64k but
who cares? It doesn't participate in anything directly so it works great
and is affordable so I can blow more money on the stuff that counts. ;-)

Subject: Lab Frame-relay switch build
Hi Group,
I'm trying to reorganise my lab in order to work with InternetworkExpert
Labs.
They seem to utilise a lot of serial/frame-relay links and i have need to
build new Frame-relay switch with 8 serial interfaces.
I was thinking to use 2x WIC-2T and 1x NM-4A/S card in a signle Cisco2620
router, when read the following about 2T cards on cisco.com:
Synchronous support with a maximum speed of 2.048 Mbps per port.
-
Supports one port at 8 Mbps when used in NM-1FE1R2W, NM-1FE2W,
NM-2FE2W, or
NM-2W<http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_not
e
09186a00800b1155.shtml>,
or Cisco 2600 chassis WIC slots. All other WIC ports on that network
module
or Cisco 2600 chassis must not be used.
-
Supports two ports at 4 Mbps each when used in NM-1FE1R2W, NM-1FE2W,
NM-2FE2W, or
NM-2W<http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_not
e
09186a00800b1155.shtml>,
or Cisco 2600 chassis WIC slots. All other WIC ports on that network
module
or Cisco 2600 chassis must not be used.
-
Supports 8 Mbps on all ports simultaneously on 2691, 3725, and 3745.
No restrictions. Maximum six ports at 8 Mbps each
As I'm about to order those two WIC-2T cards, could anyone confirm that a
combination of two WIC-2T cards is supported? I'm not sure the note above is
valid only when the interfaces are run at 4 or 8mbit/s or it is a general
limitation.
thanks for your help!
