S0/DS1-0@SDA123456789ABC = 0000 1111 0000 0000 0000 0001 (24 bits for T1. Channel number begins with 1 to 24 from left to right. In the case of PRI, the last bit specifies the D-Channel, which does not get affected. In this example, the 5th through 8th B-Channels are out of service.)
S1/DS1-0@DLS2-CM136-VG200-2.SELSIUSCMLAB.CISCO.COM = 0000 0000 0000 0000 0000 0000 1111 1111 (32 bits for E1. B-Channel number begins with 1 to 32 from left to right. The 16th channel specifies the D-Channel. The last bit does not affect any channel. In this example, the 25th through 31st channels are marked out of service.)
The above text describes a T1 and E1 PRI setting respectively. In both cases, the last bit is a 1 which doesnt really affect any thing. In the case of a T1, the last bit is the D-channel, but in case of a E1, last bit is not the Dchannel. So in case of a E1, should the 16th channel be set to 1 or 0 ?
I've done a few partial PRIs in the UK, but they've all been 8/12 channels so far and I've just used the first 8/12 bits set to 0, with all 1s for the rest.
Note the line about E1 says 'the 16th channel specifies the D-channel' - I'd just ensure that is set to 1, though I doubt it would disable it either way (as with the T1). It mentions the last bit doesn't affect any channel (as there are 32 bits to cover 30 channels + 1B channel) but is a little vague about the 16th....

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
