    The VWICs also support a limited channelized capability where the T1
    or E1 service can be flexibly split into two fractional channel
    groups. Thus a single physical port can provide connection to two
    other sites. (Note:  when choosing this mode only a single port can be
    supported in each WIC slot.) Initially this capability is only
    supported on the Cisco 2600. (See Table 2 for details.)

Depends on your value of pricey, but going the ebay approach should be
<$9k.
