* Channel Group refers to bonding of one or more timeslots into a single HDLC-framed serial connection for IP data traffic connectivity. This is used for
HDLC, Frame Relay and MLPPP serial WAN connections.
** Ds0 Group refers to Bonding of one or more timeslots into a single TDM voice connection using Channel Associated Signaling (CAS) such as E&M,
FXS or FXO. This is used for TDM PBX or PSTN connections and typically deployed only on T1.
*** PRI Group refers to bonding of two or more timeslots into a single TDM connection using ISDN signaling. This is typically used for TDM PBX or
PSTN voice and video connections on T1 and E1, and also for data WAN connections on E1. Each call on the PRI is individually indicated as being a
voice, video or data call with the ISDN bearer capability delivered with the call. Signaling is done on the D-channel, which is always channel 24 on a
T1, and channel 31 on an E1.
**** TDM Group refers to cross-connecting one or more timeslots from one TDM interface to another. This is used to groom channels from different
access points onto a combined T1 or E1 uplink. Since the router merely cross-connects and does not interpret or route the traffic from the ingress
interface to the egress interface, the traffic type (voice, video and data) is transparent to the router.
