interface numbering Cisco 1721 router

[InDenial]

Hi all,

I was working on a 1721 today and I saw something wich I do not quite onderstand..

We have a 1721 with teh following modules:

WIC Slot 0: (WIC-1ENET=)
Ethernet 10bT WAN daughter card-Version 4 TLV Cookie Format

WIC/VIC Slot 1: (VWIC-1MFT-G703=(
E1 G703 (1 port) Multi-Flex Trunk WAN daughter card

If I do a show ip int brie I get the following:

FastEthernet0 xxx.xxx.xxx.xxx YES NVRAM up up
Loopback0 xxx.xxx.xxx.xxx YES NVRAM up up
Serial0:0 xxx.xxx.xxx.xxx YES NVRAM up up
Virtual-Access1 unassigned YES unset up up
Ethernet0 unassigned YES TFTP administratively down down

before I did a show diag and saw wich modules were in the router I did the show ip int brie and I assumed that the serial0:0 was an interface on a module in slot 1.

In the config there is:

controller E1 0
channel-group 0 timeslots 1-31

My question now is... can you normally assume that if an interface is called serial1 that it is on a module in slot 1?
if so.. why doesn't it show serial1:0 ?
could it be that because of the configuration of the E1 controller E1 0 the serial interface is called Serial0:0 ?
